An Organic Mineral Adhesive Bone Graft: A Preclinical Study.

The development of a successful bone grafting technology with cohesive and adhesive properties has been an elusive goal for dental and orthopedic researchers. Tetracalcium phosphate combined with phosphoserine (TTCP-PS) is a synthetic, injectable, cohesive, self-setting, mineral-organic wet-field adhesive. The objective of this study was to evaluate four formulations of TTCP-PS in comparison to the conventional grafting materials, Bioglass and deproteinized cancellous bovine bone with a bioresorbable collagen membrane in standardized defects created in the angle of the rat mandible.

DNMT3B splicing dysregulation mediated by SMCHD1 loss contributes to DUX4 overexpression and FSHD pathogenesis.

Structural maintenance of chromosomes flexible hinge domain-containing 1 (SMCHD1) is a noncanonical SMC protein and an epigenetic regulator. Mutations in SMCHD1 cause facioscapulohumeral muscular dystrophy (FSHD), by overexpressing DUX4 in muscle cells. Here, we demonstrate that SMCHD1 is a key regulator of alternative splicing in various cell types.

Trends Favoring an Anatomical Approach to Radiofrequency Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit.

Background: Epicardial radiofrequency catheter ablation (RFCA) of idiopathic ventricular arrhythmias (VAs) originating from the left ventricular summit (LVS) is challenging because of the anatomic barriers. On the other hand, RFCA at the endocardial sites near the earliest epicardial activation site of LVS-VAs (anatomic approach) has proven successful. The evolving trends in the approaches and outcomes of RFCA of LVS-VAs at a single center were evaluated.

CAR T-cell therapy: A collaboration between authorized treatment centers and community oncologists.

With the approval of the first CAR T-cell products for hematological malignancies in 2017, these autologous cell therapies have changed the treatment paradigm for patients with relapsed or refractory (r/r) non-Hodgkin lymphoma (NHL), who have a poor prognosis and few effective treatment options. Despite the demonstrated clinical benefit in patients with r/r diffuse large B-cell lymphoma, mantle cell lymphoma, and follicular lymphoma, many patients who are eligible for CAR T-cell therapies do not receive them or are treated with CAR T cells as a later line of therapy at advanced stages of disease. Several barriers exist for referring patients to an authorized treatment center (ATC) for CAR T-cell therapy.
