A topographic approach to the markers of macrophage/microglia and other cell types in high grade glioma.

In glioblastoma, glioma-associated microglia/macrophages (GAMs) represent the major population of tumor infiltrating cells, with up to one half of the cells of the tumor mass. Recent studies have shown that microglia are involved in the maintenance of immunological homeostasis and protection against autoimmunity. However, despite the growing body of evidence on the topic, many aspects are yet to be clarified.

MARC1 downregulation reduces hepatocyte lipid content by increasing beta-oxidation.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a global epidemic. MASLD has a strong genetic component, and a common missense variant (rs2642438) in the mitochondrial amidoxime-reducing component 1 (MARC1) gene confers protection against its onset and severity. However, there are contrasting results regarding the mechanisms entangling this protection.

Noninvasive Assessment of portal Hypertension in Patients With Primary Biliary Cholangitis is Affected by Severity of Cholestasis.

Background & Aims: Noninvasive tests (NITs) for ruling-out clinical significant portal hypertension (CSPH) and high-risk varices (HRVs) in patients with primary biliary cholangitis (PBC) and compensated advanced chronic liver disease (cACLD) are lacking. We evaluated NITs in these patients and the influence of cholestasis on their performance.

Methods: Consecutive patients from the "Italian PBC registry" and 2 United Kingdom large-volume PBC referral centers with upper endoscopy within 6 months from biochemical evaluation and transient elastography were included.

Cerebellopontine angle pilocytic astrocytoma in adults: A systematic review.

Background: In adults, the cerebellopontine angle (CPA) pilocytic astrocytoma (PA) is very rare. This tumor has radiological features similar to those of a vestibular schwannoma in the few cases reported in the literature.

Methods: In this study, we conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol and scrutinized all original studies pertaining to pontocerebellar angle PA in adult patients.

Performance of ultrasound-guided attenuation parameter and 2D shear wave elastography in patients with metabolic dysfunction-associated steatotic liver disease.

Purpose: To assess the performance and the reproducibility of ultrasound-guided attenuation parameter (UGAP) and two-dimensional shear wave elastography (2D-SWE) in patients with biopsy-proven metabolic dysfunction-associated steatotic liver disease (MASLD).

Methods: This study included consecutive adult patients with MASLD who underwent ultrasound with UGAP, 2D-SWE and percutaneous liver biopsy. The median values of 12 consecutive UGAP measurements were acquired by two independent radiologists (R1 and R2).
