Chronic total occlusion recanalization still represents the final frontier in percutaneous coronary intervention. Retrograde chronic total occlusion recanalization has recently become an essential complement to the classical antegrade approach. In experienced hands, the retrograde technique currently has a high success rate with a low complication profile, despite frequent utilization in the mo...

BACKGROUND Recent evidence supports the use of robotic surgery for the minimally invasive surgical management of adrenal masses. OBJECTIVE To describe a contemporary step-by-step technique of robotic adrenalectomy (RA), to provide tips and tricks to help ensure a safe and effective implementation of the procedure, and to compare its outcomes with those of laparoscopic adrenalectomy (LA). DE...

Objective. To investigate the accuracy of dies obtained from single-step and 2-step double-mix impressions. Material and Methods. Impressions (n = 10) of a stainless steel die simulating a complete crown preparation were performed using a polyether (Impregum Soft Heavy and Light body) and a vinyl polysiloxane (Perfectim Blue Velvet and Flexi-Velvet) in two consistencies, in one or two (without ...

The concept of minimal preparation is more than 25 years old. Interest in conservative treatments is being revisited as dentistry embraces thinner ceramic veneers and adhesive bonding agents that keep preparations in enamel. Experience and professional knowledge help determine appropriate treatments based on patients' clinical situations and esthetic demands. This article reviews the veneer mod...

A new mathematical justification for using real interpolation points in model reduction is given, with the help of optimal time function approximations by transformed Legendre polynomials. Based on that, two reduction schemes are proposed: The first one applies a projection to the original model and matches 2q moments, similar to known rational Krylov methods. The second one matches q moments w...

This study demonstrates the effectiveness of a step-by-step carving technique that is quickly and efficiently mastered by dental students. Thirty-six final-year dental students volunteered to participate in this study. The students were given pre-prepared lower right first molar simulation teeth that had the occlusal half replaced in carving wax. The study was conducted in three time phases: pr...

The most consistent indications for USguided CB of breast are listed on Table 1. Patients with imaging studies revealing findings as BI-RADS category 4 (approximately 20% to 40% are malignant) or BI-RADS 5 (about 95% are malignant) must undergo biopsy. Findings classified as BI-RADS 3 present a lower risk for malignancy (< 2.0%), but such findings do require short-term follow-up. In such catego...

low solubility and dissolution rate are the primary challenges in the drug development which substantially impact the oral absorption and bioavailability of drugs. due to the poor water solubility, albendazole (abz) is poorly absorbed from the gastrointestinal tract and shows low oral bioavailability (5%) which is a major disadvantage for the systemic use of abz. to improve the solubility and d...
