Prevalence of HER3 Expression in Pancreatic Cancer Patients Treated With Systemic Chemotherapy.

Background: Although activation of human epidermal growth factor receptor 3 (HER3) is linked to resistance to targeted therapies in several cancer types, the HER3 expression profile during pancreatic cancer treatment remains unknown.

Aims: We evaluated the HER3 expression status after chemotherapy for pancreatic cancer and its association with clinicopathological features and clinical outcomes.

Materials & Methods: We included patients with pancreatic cancer who underwent chemotherapy and whose post-treatment archival tissue specimens were collected.

Focused Ultrasound Pallidothalamic Tractotomy in Cervical Dystonia: A Pilot Study.

Background: No clinical trials have been reported on the use of focused ultrasound (FUS) for treating cervical dystonia.

Objective: We aimed to confirm the efficacy and safety of FUS pallidothalamic tractotomy for cervical dystonia.

Methods: This was a prospective, open-label, non-controlled pilot study.

Washout-parametric imaging with Sonazoid for enhanced differentiation of focal liver lesions.

Purpose: The study aimed to compare the diagnostic performance of washout-parametric imaging (WOPI) with that of conventional contrast-enhanced ultrasound (cCEUS) in differentiating focal liver lesions (FLLs).

Methods: A total of 181 FLLs were imaged with contrast-enhanced ultrasound using Sonazoid, and the recordings were captured for 10 minutes in a prospective setting. WOPI was constructed from three images, depicting the arterial phase (peak enhancement), the early portal venous phase (1-minute post-injection), and the vasculo-Kupffer phase (5 or 10 minutes post-injection).

Ultrahigh-resolution imaging of biogenic phosphorus and molybdenum in palaeoproterozoic gunflint microfossils.

Phosphorus and molybdenum play important roles in the formation of microbial cell structures and specific enzymes crucial for metabolic processes. Nevertheless, questions remain about the preservation of these elements within ancient microfossils. Here, we present shape-accurate ion images capturing phosphorus and molybdenum on Palaeoproterozoic filamentous microfossils by pioneering a methodology using lateral high-resolution secondary ion mass spectrometry.

Favorable liver and skeletal muscle changes in patients with MASLD and T2DM receiving glucagon-like peptide-1 receptor agonist: A prospective cohort study.

To investigate changes in skeletal muscle mass and fat fraction in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes mellitus (T2DM) undergoing treatment with Semaglutide for 6months. This single-arm pilot study included 21 patients with MASLD who received semaglutide for T2DM. Body weight, metabolic parameters, liver enzymes, fibrosis markers, skeletal muscle index (cm2/m2), and fat fraction (%) at the L3 level using the two-point Dixon method on magnetic resonance imaging (MRI), as well as liver steatosis and liver stiffness assessed using MRI-based proton density fat fraction (MRI-PDFF) and MR elastography, respectively, were prospectively examined before and 6 months after semaglutide administration.
