Can ICD Electrograms Help Ventricular Tachycardia Ablation?: Results From the Multicenter Randomized AIDEG-VTA Trial.

Background: The results of ablation of sustained monomorphic ventricular tachycardia (SMVT) are suboptimal. For many patients with implantable cardioverter-defibrillators (ICDs), ICD electrograms (ICD-EGs) provide the only available information on SMVT. ICD-EGs have the ability to distinguish morphologically distinct SMVT and can be used for pace mapping.

Development of Nanofluid-Based Solvent as a Hybrid Technology for In-Situ Heavy Oil Upgrading During Cyclic Steam Stimulation Applications.

This paper evaluates solvent-based nanofluids for in situ heavy oil upgrading during cyclic steam stimulation (CSS) applications. The study includes a comprehensive analysis of the properties and characteristics of nanofluids, as well as their performance in in situ upgrading and oil recovery. The evaluation includes laboratory experiments to investigate the effects of the nanoparticle's chemical nature, asphaltene adsorption and gasification, heavy oil recovery, and quality upgrading.

Computational modeling of maxillary canine orthodontic movement.

Objectives: The current study aims to explore the stress distribution along the roots of palatally positioned maxillary canines during orthodontic movement using a novel computational spring model.

Methods: An experimental analysis based on the spring-model was utilized to calculate Orthodontic Tooth Movement (OTM) and the resulting stresses. Two sets of experiments were conducted: the first set compared stresses on a canine resulting from a single force and a force-couple, while the second set simulated canines' traction during instantaneous movement with varying original tooth angulations using different off-the-shelf orthodontic coils.

Inflammatory response toward a Mg-based metallic biomaterial implanted in a rat femur fracture model.

The immune system plays an important role in fracture healing, by modulating the pro-inflammatory and anti-inflammatory responses occurring instantly upon injury. An imbalance in these responses can lead to adverse outcomes, such as non-union of fractures. Implants are used to support and stabilize complex fractures.

[The place of the psychologist in the orthopedics department].

The essential place of the psychologist in the orthopedics department of Pitié-Salpêtrière is to relieve the suffering of polytraumatized patients, to work in a multidisciplinary manner, to participate in the staff of the department to have complete information of the patients, to give an informed opinion on the psychological state of the patient, so as to help in the discussion for making decisions on their trajectory. The role of the psychologist is part of the overall care of patients, care which sometimes extends to the family, the patient's loved ones and the teams who care for them.
