Evaluation of the presence of the premaxillary-maxillary suture in growing patients: A retrospective CBCT study.

Background: The premaxillary-maxillary suture (PMS) is related to midface development, but its exact closure period remains undefined. Some authors consider the premaxilla as an independent bone with potential for orthopaedic stimulation, while others see it as a phylogenetic vestige.

Objective: To determine the prevalence of the premaxillary-maxillary suture (PMS) in cone beam computed tomography (CBCT) images of patients aged 6 to 16years, according to age and sex, treated at the Dental Clinic of the Pontificia Universidad Católica de Chile's Oral Imaging Service between 2015 and 2023.

Tumor burden quantified by Soluble B-Cell Maturation Antigen and Metabolic Tumor Volume determine myeloma CAR-T outcomes.

Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a breakthrough treatment for relapsed and refractory multiple myeloma (RRMM). However, these products are complex to deliver and alternative options are now available. Identifying biomarkers that can predict therapeutic outcomes is crucial for optimizing patient selection.

Enantioselective [2π + 2σ] Photocycloaddition Enabled by Brønsted Acid Catalyzed Chromophore Activation.

Bicyclo[2.1.1]hexanes have emerged as valuable scaffolds for the design of new pharmaceutical and agrochemical active ingredients.

A pre-post trial to examine biological mechanisms of the effects of time-restricted eating on symptoms and quality of life in bipolar disorder.

Background: The primary objective of this trial is to examine the mechanisms of time-restricted eating (TRE) as an adjunct to psychiatric care for people with bipolar disorder (BD) with sleep or circadian disruptions. This study builds on prior studies of circadian disruption in BD as well as growing evidence that TRE improves circadian functioning.

Methods: One-hundred fifty participants diagnosed with BD 1 or II will be recruited via advertising in the local community.
