The impact of signaling pathways on the desmosome ultrastructure in pemphigus.

Introduction: The autoantibody-driven disease pemphigus vulgaris (PV) impairs desmosome adhesion in the epidermis. In desmosomes, the pemphigus autoantigens desmoglein 1 (Dsg1) and Dsg3 link adjacent cells. Dsgs are clustered by plaque proteins and linked to the keratin cytoskeleton by desmoplakin (Dp).

A Comparison of In-Person and Telehealth Treatment Modalities using the SpeechVive Device.

Telehealth is increasing popular as a treatment option for people with Parkinson disease (PD). The SpeechVive device is a wearable device that uses the Lombard effect to help patients speak more loudly, slowly, and clearly. This study sought to examine the effectiveness of the device to improve communication in people with PD, delivered over a telehealth modality as compared to in-person, using implementation science design.

Strand-Swapped SH3 Domain Dimer with Superoxide Dismutase Activity.

The design of metalloproteins allows us to better understand metal complexation in proteins and the resulting function. In this study, we incorporated a Cu-binding site into a natural protein domain, the 58 amino acid c-Crk-SH3, to create a miniaturized superoxide dismutase model, termed SO1. The resulting low complexity metalloprotein was characterized for structure and function by circular dichroism and UV spectroscopy as well as EPR spectroscopy and X-ray crystallography.

New physiological insights using multi-TE ASL MRI measuring blood-brain barrier water exchange after caffeine intake.

Objectives: Caffeine, a known neurostimulant and adenosine antagonist, affects brain physiology by decreasing cerebral blood flow. It interacts with adenosine receptors to induce vasoconstriction, potentially disrupting brain homeostasis. However, the impact of caffeine on blood-brain barrier (BBB) permeability to water remains underexplored.

Information Behaviour and Knowledge of Patients Before Radical Prostatectomy.

Background/objectives: Robot-assisted and open radical prostatectomy (RARP and ORP) are established procedures for localized prostate cancer, with comparable oncological and functional outcomes. Little is known about patients' knowledge of both procedures. This study aimed to examine comparatively the informational behaviour and knowledge of patients undergoing ORP vs.
