A method is described of fine-needle aspiration biopsy of liver metastases under direct guidance by ultrasonic scanning. Comparing the results with this technique and those with liver biopsy by Menghini's method in 18 cases, we found that it was more accurate than the usual blind method.

Therapeutic Potential and Mechanistic Insights of a Novel Synthetic α-Lactalbumin-Derived Peptide for the Treatment of Liver Fibrosis.
J Clin Exp Hepatol
December 2024
Biochemistry and Molecular Biology Department, Theodor Bilharz Research Institute, Giza, Egypt.
Background: Liver fibrosis is a serious global health issue, but current treatment options are limited due to a lack of approved therapies capable of preventing or reversing established fibrosis.
Aim: This study investigated the antifibrotic effects of a synthetic peptide derived from α-lactalbumin in a mouse model of thioacetamide (TAA)-induced liver fibrosis.
Methods: analyses were conducted to assess the physicochemical properties, pharmacophore features, and docking interactions of the peptide.
Primary hepatic carcinosarcoma: a case report with insights from retrospective analysis of clinical characteristics and prognostic factors.

Primary hepatic carcinosarcoma (HCS) is an extremely rare malignant tumor with carcinomatous and sarcomatous elements. Few reported cases of HCS exist, especially with sufficient records to describe imaging and pathological features, making the diagnosis, treatment, and prognosis of HCS a significant challenge for physicians. Here, we report a case of HCS with spontaneous rupture as the initial symptom in a 77-year-old elderly male who was admitted with right upper abdominal pain for 8 days.

Highly sensitized (HS) patients in need of kidney transplantation (KTx) typically spend a longer time waiting for compatible kidneys, are unlikely to receive an organ offer, and are at increased risk of antibody-mediated rejection (AMR). Desensitization using imlifidase, which is more rapid and removes total body immunoglobulin G (IgG) to a greater extent than other methods, enables transplantation to occur between HLA-incompatible (HLAi) donor-recipient pairs and allows patients to have greater access to KTx. However, when the project was launched there was limited data and clinical experience with desensitization in general and with imlifidase specifically.

Organ fibrosis, considered as a major global health concern, is a pathological condition often occurring after tissue injury in various organs. The pathogenesis of fibrosis involves multiple phases and multiple cell types. Dopamine is involved in various life activities by activating five receptors (D1, D2, D3, D4, D5).

January 2025
Cincinnati Children's AI Imaging Research (CAIIR) Center, Cincinnati, OH, United States.
Background: Traditional liver fibrosis staging via percutaneous biopsy suffers from sampling bias and variable inter-pathologist agreement, highlighting the need for more objective techniques. Deep learning models for disease staging from medical images have shown potential to decrease diagnostic variability, with recent weakly supervised learning strategies showing promising results even with limited manual annotation.
Purpose: To study the clustering-constrained attention multiple instance learning (CLAM) approach for staging liver fibrosis on trichrome whole slide images (WSIs) of children and young adults.
