26. Cleaning effectiveness of a nickel-titanium ultrasonic tip in ultrasonically activated irrigation: a SEM study
Abstract In endodontic treatment, regardless of the instrumentation technique, the presence of a smear layer covering contaminated dentin walls is always a concern. Thus, irrigation plays an essential role in reducing bacterial load. To enhance irrigation effectiveness, different ultrasonic activation methods and the use of different tips have been studied.

27. Evidence-based review of methods used to reduce pain after excisional hemorrhoidectomy
RESUMO Introdução: A hemorroidectomia excisional (HE) é um dos procedimentos anorretais mais comumente realizados. Apesar dos resultados satisfatórios da hemorroidectomia excisional, a dor percebida pelos pacientes após o procedimento pode ser uma sequela angustiante. Esta revisão teve como objetivo buscar na literatura atual as evidências existentes

28. Ultrasonic tips as an auxiliary method for the instrumentation of oval-shaped root canals
Abstract To evaluate the influence of novel ultrasonic tips as an auxiliary method for the rotary preparation of flattened/oval-shaped canals. Forty-five mandibular incisors were selected and divided into one of three experimental groups (n = 15): Group PFCP – ProDesign Logic 25/.05 + Flatsonic + Clearsonic + Prodesign Logic 40/.01; Group FCP – Flatsonic

30. Modelo ex-vivo com coração bovino: proposta para treinamento de dissecção microscópica e de microanastomoses vasculares.
RESUMO O treinamento é um processo que exige paciência e constante prática. A execução de procedimentos microscópicos está presente no dia a dia de diversas especialidades cirúrgicas, mas infelizmente modelos experimentais não são de fácil de acesso. Propomos um modelo com coração bovino usado por residentes e jovens cirurgiões no treinamento d

31. Solid-phase extractions in flow analysis
ABSTRACT Coupling solid-phase extraction (SPE) to flow systems has promoted a synergistic development. Whereas SPE mechanization leads to improved precision and higher sample throughput, as well as diminishes systematic errors and contamination risks, analyte concentration and separation from the sample matrix provides a remarkable impact on detectability an

32. Implantation of a biodegradable rectum balloon implant: Tips, Tricks and Pitfalls
ABSTRACT Introduction: A rectum balloon implant (RBI) is a new device to spare rectal structures during prostate cancer radiotherapy. The theoretical advantages of a RBI are to reduce the high radiation dose to the anterior rectum wall, the possibility of a post-implant correction, and their predetermined shape with consequent predictable position. Objecti

34. Micropropagation of Cyrtopodium paludicolum (Orchidaceae) from root tip explants
Abstract An efficient protocol for in vitro plant propagation of Cyrtopodium paludicolum has been developed using root tips dissected from well-developed seedlings. Root tips were cultured on Knudson medium supplemented with α-naphthaleneacetic acid (NAA), and/or thidiazuron (TDZ). TDZ did not induce protocorm-like bodies (PLBs) in the NAA absence, indicati
