Numerous types of prosthodontics surgical guides, with and without metallic sleeves, have been found to be useful in clinical studies. The aim this vitro research was compare the time required complete procedure two differently designed prosthetic templates. Ten identical prototype models mandible based on a CBCT optical scan partially edentulous patient missing teeth numbers 37, 46, 47 were pr...

We investigated the performance of a new collection tube for the preparation of EDTA anti-coagulated plasma for viral load testing. HCV RNA copy numbers were measured with a commercially available assay (the Amplicor HCV MonitorTM test kit). Blood specimens were collected from HCV-seropositive individuals in the VACUTAINER Brand Plasma Preparation TubeTM and a control, non-gel separator VACUTAI...

Recently, there has been great interest in the synthesis and application of various kinds of nanostructured noble metals such as platinum, gold and silver. Nanostructured silvers have been widely investigated as antimicrobial materials, bio-sensors, catalysts, and advanced materials exhibiting surface plasmon resonance and surface enhanced Raman scattering. All this research is mainly based on ...

The obligate intracellular bacterium Lawsonia intracellularis causes enteritis and poor growth in weaned pigs. Cultivation is difficult and diagnosis ante mortem is mainly based on techniques such as polymerase chain reaction. However, false negative results caused by the presence of PCR-inhibitory factors constitute a problem. This study aimed to develop and evaluate a new technique, flotation...

This document describes the RoboCup Humanoid League team NimbRo of University of Freiburg in preparation for the competition to be held in Osaka in July 2005. Our team uses a variety of robots for playing soccer: RoboSapien, Kondo, Toni, and Fritz. These robots are either constructed in our lab, based on a construction kit, or based on a low-cost commercial robot. The paper describes the robot ...

When Tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. They hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. One of this type of colloid agents, is Tc-99-tin-colloid which is prepar...

The Sonogashira cross-coupling, a key step in the syntheses of the mGlu₅ antagonists MMPEP and MTEP, provided an improved three-step method for the preparation of MMPEP in 62% overall yield. Using Spartan molecular modeling kit an explanation for the failure to employ analogues method in the synthesis of MTEP was sought. The DFT calculations indicated that meaningful isolated yields were obtain...

Objectives: Ceramics have advantages such as optimal esthetics and biocompatibility. However, in the oral environment, they are subjected to high levels of stress due to masticatory forces, saliva, thermal changes and alterations of pH, which increase their risk of fracture. Since replacement of these restorations is costly and time-consuming, composite resin is often used for intraoral repair ...

cystic hydatid disease (hydatidosis) is the most serious tape-worm infection prevalent in the cattle and sheep raising area of the world. hydatidosis in man (as an accidental host) caused by infection with the ova containing larval stage of echinococcus spp. in the last decade different techniques have been employed for the serological diagnosis of hydatid disease, such as iha, ifa, elisa, ccle...
