[18F]Tetrafluoroborate: a new NIS PET/CT radiopharmaceutical. An overview focused on differentiated thyroid cancer.

Background: In relapsing differentiated thyroid cancer (DTC), the in vivo evaluation of natrium-iodine symporter (NIS) expression is pivotal in the therapeutic planning and is achieved by [131/123I]Iodine whole-body scan. However, these approaches have low sensitivity due to the low sensitivity due to the low resolution of SPECT. [18F]Tetrafluoroborate (TFB) has been proposed as a viable alternative, which could outperform [131/123I]Iodine scans owing to the superior PET resolution.

Feasibility and Clinical Efficacy of Focal Pulsed Field Ablation in Patients With Non-Pulmonary Vein Triggered Atrial Arrhythmia From the Superior Caval Vein.

Introduction: In patients with atrial arrhythmias originating from the superior vena cava (SVC), the use of radiofrequency energy to isolate the SVC is associated with a significant risk of injury both to the phrenic nerve and the sinus node. Pulsed field ablation (PFA) may overcome the disadvantages of thermal energy and improve both ablation efficacy and safety.

Objective: We report the feasibility, safety, and clinical efficacy of focal monopolar PFA in patients with the origin of their atrial arrhythmia in the SVC.

The Expression of HPV-16 E5 Oncoprotein Impacts the Transcript Profiles of FGFR2 and EMT-Related Genes in Preneoplastic Anal Epithelium Lesions.

Anal Squamous Cell Carcinoma (SCCA) is a rare Human Papillomavirus type 16 (HPV16)-associated carcinoma whose pathogenesis is still poorly understood. Recent studies based on biopsy and Next Generation Sequencing (NGS) approaches have linked the viral episomal status to aggressive SCCA phenotypes, suggesting a potential role of the 16E5 oncoprotein in tumor development. Our previous findings indicated that 16E5 induces Fibroblast Growth Factor Receptor 2 (FGFR2) isoform switching, aberrant mesenchymal FGFR2c expression, Epithelial Mesenchymal Transition (EMT), and cell invasion in various in vitro human keratinocyte models, as well as in the in vivo context of cervical Low-grade Squamous Intraepithelial Lesions (LSILs).

Atrial natriuretic peptide (ANP) modulates stress-induced autophagy in endothelial cells.

Atrial natriuretic peptide (ANP), a cardiac hormone involved in the regulation of water/sodium balance and blood pressure, is also secreted by endothelial cells, where it exerts protective effects in response to stress. Autophagy is an intracellular self-renewal process involved in the degradation of dysfunctional cytoplasmic elements. ANP was recently reported to act as an extracellular regulator of cardiac autophagy.

Metabolic and dopaminergic correlates of intellectual enrichment in de-novo Parkinson's disease patients.

Background: Cognitive reserve (CR) is an expression of brain resilience in response to damage. Education, occupational experience and leisure activities are thought to increase CR and have beneficial effects on global cognition and cognitive decline in Parkinson's disease (PD). We aimed to disclose brain metabolic and dopaminergic correlates of CR in de-novo PD patients.
