Tunable magnetothermal properties of cobalt-doped magnetite-carboxymethylcellulose ferrofluids: smart nanoplatforms for potential magnetic hyperthermia applications in cancer therapy.

Magnetite nanoparticles are one of the most promising ferrofluids for hyperthermia applications due to the combination of unique physicochemical and magnetic properties. In this study, we designed and produced superparamagnetic ferrofluids composed of magnetite (FeO, MION) and cobalt-doped magnetite (Co -MION, = 3, 5, and 10% mol of cobalt) nanoconjugates through an eco-friendly aqueous method using carboxymethylcellulose (CMC) as the biocompatible macromolecular ligand. The effect of the gradual increase of cobalt content in FeO nanocolloids was investigated in-depth using XRD, XRF, XPS, FTIR, DLS, zeta potential, EMR, and VSM analyses.

Current-Mode Self-Amplified CMOS Sensor Intended for 2D Temperature Microgradients Measurement and Imaging.

This paper presents the design of a current-mode CMOS self-amplified imager operating in dark conditions, for thermal imaging, which provides an innovative solution for precision thermal contact mapping. Possible applications of this imager range from 3D CMOS integrated circuits to the study of in-vivo biological samples. It can provide a thermal map, static or dynamic, for the measurement of temperature microgradients.

Multidisciplinary oral rehabilitation in partially edentulous adult patients with malocclusion: A cross-sectional survey study.

Background: A cross-sectional survey was conducted to gather information regarding the opinion of Brazilian specialists in both orthodontics and implantology on multidisciplinary oral rehabilitation in partially edentulous patients with malocclusion.

Material And Methods: A total of 305 specialists participated in a telephone survey and answered an ad hoc 10-item questionnaire, including the request of total skull cone-beam tomographies (CBCT) and the use of 3D digital planning software, the best moment of treatment to place dental implants, and the integration of orthodontics in implantology.

Results: Most participants did not request CBCT (90.

Consumer willingness to pay for a hypothetical Zika vaccine in Brazil and the implications.

Unlabelled: ABSTRACT  Background: Zika virus is a newly emerging infection, associated with increasingly large outbreaks especially in tropical countries such as Brazil. A future Zika vaccine can contribute to decreasing the number of cases and associated complications. Information about consumers' willingness to pay (WTP) for a hypothetical Zika vaccine can help price setting discussions in the future in Brazil, starting with the private market.

Cross-cultural Adaptation of the Oral Anticoagulation Knowledge Test to the Brazilian Portuguese.

Patients' knowledge about oral anticoagulant therapy may favor the achievement of therapeutic results and the prevention of adverse pharmacotherapy-related events. Brazil lacks validated instruments for assessing the patient's knowledge about treatment with warfarin. This study aimed to perform the cross-cultural adaptation of the Oral Anticoagulation Knowledge (OAK) Test instrument from English into Portuguese.
