Non-invasive estimation of pressure differences using 2D synthetic aperture ultrasound imaging offers a precise, low-cost, and risk-free diagnostic tool. Unlike invasive techniques, this preserves natural blood flow and avoids the limitations of devices that occupy lumen space. This paper evaluates a previously published estimator, modified to incorporate Singular Value Decomposition (SVD) echo-cancellation, using data from ten healthy volunteers and one patient.

Objective: Pediatric brain tumor survivors (PBTS) are at risk for neurocognitive late effects that can resemble symptoms of cognitive disengagement syndrome (CDS). In the current study, we compared the CDS symptoms of PBTS to those of healthy comparison classmates (CC) and examined whether CDS might explain group differences in depressive symptoms. We also explored whether CDS symptoms were associated with engagement-based coping strategies and stress responses, thereby testing one mechanism by which CDS could lead to affective difficulties.

Hyperpolarized-C magnetic resonance imaging (HP-C MRI) was used to image changes in C-lactate signal during a visual stimulus condition in comparison to an eyes-closed control condition. Whole-brain C-pyruvate, C-lactate and C-bicarbonate production was imaged in healthy volunteers (N = 6, ages 24-33) for the two conditions using two separate hyperpolarized C-pyruvate injections. BOLD-fMRI scans were used to delineate regions of functional activation.

Introduction: Recent studies have shown that capsaicin improves the pharyngeal swallowing reflex. However, the mechanism by which capsaicin alters mastication and oesophageal function remains unclear. This study aimed to investigate the effects of capsaicin on masticatory and oesophageal function.

Background: Surface electromyography (sEMG) has been used in a wide range of studies conducted in the field of dysphagia.
Objectives: The main aim of this case-control study is to obtain how submental and infrahyoid sEMG signals differ based on residue, penetration and aspiration.
Methods: A total of 100 participants (50 patients with suspected dysphagia and 50 healthy controls) were enrolled in the present study.
