Bond strength of self-adhesive resin cement to dentin using different adhesion protocols

2022

Background The treatment of dentin before the use of self-adhesive cements is still a crucial point to achieve the best bond strength values. The objective of this study was to evaluate the bond strength between dentin and composite resin using different adhesion strategies with self-adhesive resin cement. Material and Methods Forty healthy third human molars were randomly divided into 4 groups (n = 10): CA (control); application of self-adhesive cement (Rely X U200, 3M ESPE), AD + CA: only application of conventional adhesive (Adper Single Bond 2, 3M ESPE) + self-adhesive cement, AC + AD + CA; conditioning with 37% phosphoric acid for 15 seconds + application of conventional adhesive + sel…

Criteria and treatment decisions in the management of deep caries lesions: Is there endodontic overtreatment?

2018

Background The aim of this study was to investigate the diagnostic criteria and treatment decisions in the management of deep caries lesions (DCLs). The null hypothesis tested was that DCLs are managed according to the current scientific evidence. Material and Methods A total of 288 dentists were contacted directly or by mail, and 125 (43%) were included in the study. Dentists were requested to answer a questionnaire about the routine approach to the diagnosis and treatment of DCLs. Logistic regression analyses were carried out to calculate odds ratios (OR). Results Pulp sensitivity tests were used by 65% of dentists when assessing pulpal health in cases of DCLs, particularly those who had …

Towards a Guidance System to Aid in the Dosimetry Calculation of Intraoperative Electron Radiation Therapy

2015

In Intraoperative Electron Radiation Therapy (IOERT), the lack of specific planning tools limits its applicability, the need for accurate dosimetry estimation and application during the therapy being the most critical. Recently, some works have been presented that try to overcome some of the limitations for establishing planning tools, though still an accurate guidance system that tracks, in real-time, the applicator and the patient is needed. In these surgical environments, the acquisition of an accurate 3D shape of the patient’s tumor bed in real-time is of high interest, as current systems make use of a 3D model acquired before the treatment. In this paper, an optical-based system is pre…

Additional file 4 of Co-administration of human MSC overexpressing HIF-1�� increases human CD34+ cell engraftment in vivo

2021

Additional file 4. Figure S3. Analysis of human hematopoietic engraftment in spleen. Human hematopoietic engraftment was evaluated by flow cytometry after xenotrasplantation in NOD/SCID mice. The percentage of human CD45+ cells (donor chimerism) was analyzed in total spleen samples 4 weeks after transplantation. Mice were transplanted intravenously with CD34+ cells alone or co-transplanted with MSC WT or HIF-MSC, that were administered in the right femur. Data are represented as mean of 8 experiments for mice transplanted with CD34+ cells alone, 13 experiments for mice co-transplanted with CD34+ cells and WT MSC and 15 experiments for mice transplanted with CD34+ cells and HIF-MSC. p:n.s me…

Establishing a New ECMO Referral Center Using an ICU-Based Approach: A Feasibility and Safety Study

2022

Background: A high-volume center with a multidisciplinary team is regarded as the optimal place for providing extracorporeal membrane oxygenation (ECMO). We hypothesize that an ECMO center can also be successfully created and subsequently developed entirely by intensivists in a mid-size mixed intensive care unit (ICU). Methods: A model was created for setting up a new ECMO referral center within the structure of an existing mixed ICU in a tertiary hospital. A retrospective analysis was carried out of the first 33 patients treated in the initial period of the center’s activity, from mid 2018 to the end of 2020. Results: An ECMO center was established and developed entirely based on the resou…

Hepatocyte transplantation, a step forward?

2019

Hepatocyte transplantation emerged a few decades ago as a possible strategy to overcome some of the limitations of liver transplantation, among them the availability of organ donors and the functional quality of grafts. Nowadays, allogenic cell transplantation is still to be confirmed as a viable therapeutic option for patients with hereditary metabolic liver diseases. Although we have now overseen 5 decades of basic and animal research in the field, the number of successfully treated patients remains low. Limitations in cell engraftment and selective proliferation of transplanted cells remain a constraint to the generalized use of this therapeutic approach.

Resonancia nuclear magnética en roturas del ligamento cruzado anterior : sensibilidad y concordancia con hallazgos artroscópicos

2018

To estimate the sensitivity of magnetic resonance imaging (MRI) as a diagnostic test in anterior cruciate ligament (ACL) injuries, as well as its correlation with arthroscopic findings. Methods. Retrospective analysis of 270 patients who underwent ACL reconstruction surgery in our health department between 2007 and 2017. ACL injuries were diagnosed by radiologists specialized in musculoskeletal pathology, while the correlation between radiological and arthroscopic findings was determined through statistical analysis. Results. The sensitivity of the MRI regarding diagnosis of ACL injuries was 88.5%. In addition, the correlation between radiologic and arthroscopic findings was 73.3%. In 71% o…
