Cognitive outcomes of the at-home brain balance program.

Accessibility to developmental interventions for children and adolescents could be increased through virtual, at-home delivery of training programs. Virtual childhood training programs and their effects on cognitive outcomes have not been well studied. To that end, this study examined the effects of the at-home Brain Balance® (BB) program on the cognitive task performance of children and adolescents with baseline developmental and attentional difficulties.

The PH domain in the ArfGAP ASAP1 drives catalytic activation through an unprecedented allosteric mechanism.

ASAP1 is a multidomain Arf GTPase-activating protein (ArfGAP) that catalyzes GTP hydrolysis on the small GTPase Arf1 and is implicated in cancer progression. The PH domain of ASAP1 enhances its activity greater than 7 orders of magnitude but the underlying mechanisms remain poorly understood. Here, we combined Nuclear Magnetic Resonance (NMR), Molecular Dynamic (MD) simulations and mathematical modeling of functional data to build a comprehensive structural-mechanistic model of the complex of Arf1 and the ASAP1 PH domain on a membrane surface.

Submandibular Gland Flap Reconstruction for Oropharyngeal Defects After Transoral Robotic Surgery (TORS).

Background: To describe utilization and outcomes of submandibular gland flap (SGF) reconstruction after transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC).

Methods: A multi-institutional retrospective case series of patients who underwent TORS for OPSCC followed by SGF reconstruction with harvest via transcervical approach from 1/1/2016 to 4/1/2023.

Results: In total, 14 patients underwent SGF reconstruction after TORS for OPSCC.

Metabolic profiling and antibacterial activity of tree wood extracts obtained under variable extraction conditions.

Introduction: Tree bacterial diseases are a threat in forestry due to their increasing incidence and severity. Understanding tree defence mechanisms requires evaluating metabolic changes arising during infection. Metabolite extraction affects the chemical diversity of the samples and, therefore, the biological relevance of the data.

Rare Prekallikrein Deficiency Identified During Workup of Isolated Prolonged Activated Partial Thromboplastin Time.

Prolongation of the activated partial thromboplastin time (aPTT) may signify an intrinsic factor deficiency or the presence of an inhibitor of coagulation, potentially placing a patient at increased risk for bleeding. However, a contact factor (ie, factor XII, prekallikrein, and high molecular weight kininogen) deficiency, which may also cause a prolonged aPTT, is not associated with clinical bleeding. A 71-year-old female had an isolated prolonged aPTT discovered during preoperative laboratory testing.
