introduction: smear layer (sl) is produced as a result of mechanical instrumentation of the canal(s). despite the controversies regarding its removal, the evidence-based trend has shifted towards removing and eliminating the sl. different methods have been used to remove the sl and the aim of this in vitro study was to evaluate the ability of 17% ethylenediaminetetraacetic acid (edta), 18% etid...

In his treatises Hero of Alexandria describes a range of devices for producing spectacles and generating wonder that have frequently been treated as marginal by historians of technology and science. In this paper I shall show that these devices and Hero’s emphasis on wonder-making are of central importance to the image that Hero presents of mechanics. Hero uses the concept of wonder to add an i...

We compared the effects of dipyridamole, RA-642, and mopidamol on platelet activity and thromboxane/prostacyclin balance in relation to the degree of retinal vascularization in a model of experimental streptozotocin-induced diabetes in rats. After 3 months, collagen-induced platelet aggregation in whole blood was 25% higher in diabetic animals than in nondiabetics. Dipyridamole inhibited 43% pl...

Heterogeneous embedded systems on chip (HESoCs) co-integrate a standard host processor with programmable manycore accelerators (PMCAs) to combine general-purpose computing with domain-specific, efficient processing capabilities. While leading companies successfully advance their HESoC products, research lags behind due to the challenges of building a prototyping platform that unites an industry...

Background: Sodium ionhydrogen ion (Na+-H+) exchange inhibitors are effective cardioprotective agents. The N+-H+ exchange inhibitor HOE 642 (cariporide) has undergone clinical trials in acute coronary syndromes, including bypass surgery. F'ropofol and sevoflurane are also cardioprotective v i a unknown mechanisms. The authors investigated the interaction between propofol and HOE 642 in the isch...

Prevalence of Eimeria species parasitizing rabbits (Oryctolagus cuniculus) in Taiwan were investigated. Six Eimeria species, namely: Eimeria media (prevalence, 158/642; 24.6%), Eimeria magna (101/642; 15.7%), Eimeria perforans (58/642; 9.0%), Eimeria coecicola (46/642; 7.2%), Eimeria piriformis (16/642; 2.5%), and Eimeria exigua (9/642; 1.4%) were observed. The overall prevalence of these cocci...

Resistance to cyclic flexural fatigue failure is an important feature of rotary nickel-titanium (NiTi) instruments. The aim of this study was to evaluate the cyclic flexural fatigue failure resistance of RevoS Shaper Universal rotary NiTi files and to compare it to two other rotary NiTi files with similar size and taper, the Hero Shaper and the ProFile. Fifteen each of Revo-S Shaper Universal, ...

BACKGROUND Surgical videography can provide analytical self-examination for the surgeon, teaching opportunities for trainees, and allow for surgical case presentations. This study examined if a modified GoPro Hero 4 camera with a 25 mm lens could prove to be a cost-effective method of surgical videography with enough detail for oculoplastic and strabismus surgery. METHOD The stock lens mount ...
