The sympathetic nervous system densely innervates all cardiac chambers and is a key player in cardiac control, yet this relationship has scarcely been investigated using a stem cell-based model. This study investigates the effects that sympathetic neurons (SNs) have on human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) in vitro, and whether they induce any degree of functional or structural maturity in these conventionally immature cells. SNs were isolated from neonatal rat pups, and cocultured with hPSC-CMs for up to 15 days.

Modelling inflammation-induced peripheral sensitization in a dish-more complex than expected?

Pain

February 2025

Wolfson Sensory, Pain and Regeneration Centre (SPaRC), Guy's Campus, King's College London, London, United Kingdom.

Peripheral sensitization of nociceptors is believed to be a key driver of chronic pain states. Here, we sought to study the effects of a modified version of inflammatory soup on the excitability of human stem cell-derived sensory neurons. For this, we used a preexisting and a novel stem cell line, modified to stably express the calcium sensor GCamP6f.

Reduced dose Positron Emission Tomography (PET) lowers the radiation dose to patients and reduces costs. Lower count data, however, degrades reconstructed image quality. Advanced reconstruction methods help mitigate image quality losses, but it is important to assess the resulting images from a clinical perspective.

Substrates of Sudden Cardiac Death in Hypertrophic Cardiomyopathy.

J Clin Med

February 2025

Cardiology Unit, Department of Clinical and Molecular Medicine, Sant'Andrea University Hospital, Sapienza University, 00189 Rome, Italy.

Sudden cardiac death (SCD), the most devastating complication of hypertrophic cardiomyopathy (HCM), is primarily triggered by ventricular tachycardia or fibrillation. Despite advances in knowledge, the mechanisms driving ventricular arrhythmia in HCM remain incompletely understood, stemming from an interplay of multiple pro-arrhythmic factors. Myocyte disarray and myocardial fibrosis form a structural substrate favorable to re-entrant arrhythmias by altering myocardial electrophysiological properties, while cellular abnormalities predominate in patients without evident structural remodeling.

SenSkin™: a human skin-specific cellular senescence gene set.

Geroscience

February 2025

Center for Gerotherapeutics, Division of Endocrinology and Metabolism, Department of Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

Cellular senescence gene sets have been leveraged to overcome the inadequate sensitivity or specificity of single markers. However, growing evidence of heterogeneity among tissues in senescent cell phenotypes and gene expression profiles has highlighted the need for tissue-specific gene sets. SenSkin™ was curated by an expert review of literature on cellular senescence in the skin and characterized with pathway analysis.

The MDAS questionnaire is one of a number of scales available to assess dental anxiety. It is widely used and translated into many world languages; however, it lacks an explicit theoretical backdrop to the content and structure of the measure. This paper draws upon original expositions of dental anxiety: how it develops, is maintained, and how this draws attention to a re-evaluation of the measure.

As a component of myeloablative conditioning before allogeneic hematopoietic stem cell transplantation (HSCT), Total Body Irradiation (TBI) is employed in radiotherapy centers all over the world. In recent and coming years, many centers are changing their TBI setup to a conformal isocentric technique, providing superior homogeneity and control of the target prescription dose, and more freedom for individualized organ-at-risk sparing or dose-escalation. Also, more specifically bone-marrow- and/or lymphatics-targeted therapies such as Total Marrow (+ Lymphoid) Irradiation (TMI / TMLI), and Total Lymphoid Irradiation (TLI) are established and prospectively evaluated in several centers.

Automated contouring and radiotherapy treatment planning of spine metastases using atlas-based auto-segmentation and knowledge-based planning approaches.

Br J Radiol

February 2025

Department of Medical Physics and Clinical Engineering, Guy's and St Thomas' NHS, Foundation Trust, St Thomas' Hospital, Westminster Bridge Road, London, SE1 7EH.

Objectives: Uncomplicated spine metastases are routinely treated with conventional external beam radiotherapy (cEBRT). In cEBRT, there is no delineation of target volumes or organs at risk (OAR), or attempt to optimise dose distribution to deliver conformal, homogeneous dose distributions with sparing of OAR. Atlas-based auto-segmentation (ABAS) for target volume and OAR delineation, followed by knowledge-based planning (KBP) could facilitate conformal planning of spine metastases.

Heterozygous mutations in are associated with an early-onset, progressive and often complex dystonia (DYT28). Key characteristics of typical disease include focal motor features at disease presentation, evolving through a caudocranial pattern into generalized dystonia, with prominent oromandibular, laryngeal and cervical involvement. Although -related disease is emerging as one of the most common causes of early-onset genetic dystonia, much remains to be understood about the full spectrum of the disease.
