Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Clinical Progression in Alpha‐Synuclein Positive LRRK2‐PD and Sporadic Parkinson's Disease: A Longitudinal Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background LRRK2‐Parkinson's disease (LRRK2‐PD) is biologically heterogeneous with approximately 30% lacking aggregated alpha synuclein (αSyn) in cerebrospinal fluid by seed amplification assay (SAA). Prior work has suggested slower progression in LRRK2‐PD compared to sporadic PD (sPD).

Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

Disease‐Duration–Specific Percentiles for Prospective Subtyping of Parkinson's Disease: A PPMI‐Based Study

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is clinically heterogeneous, with variable progression rates that complicate clinical trial design. The data‐driven diffuse malignant (DM), intermediate (IM), and mild‐motor predominant (MMP) subtyping model has prognostic value but lacks disease duration–specific thresholds for prospective use in disease ...

A Brainstem Radiomics Framework to Distinguish Progressive Supranuclear Palsy from Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Differentiating progressive supranuclear palsy (PSP) from Parkinson's disease (PD) can be clinically challenging. In the neuroimaging field, radiomics has emerged as a promising approach to capture subtle microstructural and textural image alterations, improving differential diagnoses.

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

open access: yesSmall, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

Quantitative Dual‐Energy CT Perfusion Versus SPECT/CT V/Q Scintigraphy for Preoperative Lung Function Assessment: A Prospective Cohort Study

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Accurate preoperative physiological assessment is critical for high‐risk patients undergoing lung resection to predict postoperative lung function. This study compared quantitative dual‐energy CT (DECT) perfusion with SPECT/CT for lobar perfusion mapping in an at‐risk oncological cohort.

Dynamic SPECT Assessment of Hepatic Function in Patients With Liver Disease: A Systematic Review and Meta‐Analysis

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Dynamic Single Photon Emission Computed Tomography (dynSPECT) is an advanced functional imaging modality that enables estimation of temporal changes in radiopharmaceutical distribution and physiological function. While dynSPECT has been employed in several clinical applications, it has not been widely applied to liver imaging ...

GMP‐compliant production, validation and dosimetry of clinical grade [18F]3‐(3‐fluoropropyl)‐2‐phenyl‐2,3‐dihydrobenzo[d]thiazole ([18F]FPBT) for oxidative stress PET imaging

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Oxidative stress plays a critical role in the pathophysiology of various diseases, yet current methods for its non‐invasive detection remain limited. This study aimed to systematically validate a superoxide‐selective PET tracer, [18F]FPBT, for the early diagnosis and therapeutic monitoring of oxidative stress‐related conditions ...

Increased Binding of [18F]Nifene, a PET Imaging Probe for α4β2* Nicotinic Acetylcholinergic Receptors in Hippocampus–Subiculum of Postmortem Human Parkinson's Disease Brain

open access: yesSynapse, Volume 80, Issue 5, September 2026.
[18F]Nifene, a PET imaging probe for α4β2* nicotinic acetylcholine receptors, was used to discretely measure changes in hippocampus (HP) and subiculum (SUB) of postmortem Parkinson's disease (PD) cases compared to cognitively normal (CN) cases. Significant increased [18F]nifene binding in PD was observed.
