Early and multiple doses of zoledronate mitigates rebound bone loss following withdrawal of RANKL inhibition.

Rebound bone loss following denosumab discontinuation is an important barrier in the effective long-term treatment of skeletal disorders. This is driven by increased osteoclastic bone resorption following the offset of RANKL inhibition, and sequential osteoclast-directed therapy has been utilised to mitigate this. However, current sequential treatment strategies intervene following the offset of RANKL inhibition and this approach fails to consistently prevent bone loss.

Hepatocyte growth factor (HGF) is a substance that stimulates the proliferation of hepatocytes which promote healing. We developed a macrophage membrane-encapsulated nanosphere drug delivery system containing HGF for the study of burn wound healing. Twenty-seven Sprague-Dawley rats were randomly divided into three groups: a saline control (NS) group, an engineered macrophage membrane-encapsulated nanospheres (ETMM@NPS) group, and an engineered macrophage membrane-encapsulated nanospheres treatment with HGF-loaded gene (HGF@ETMM@NPS) group.

Background: Hepatocellular carcinoma (HCC) encompasses rare variants like chromophobe hepatocellular carcinoma (CHCC) characterized by distinct histological features and molecular profiles.
Case Report: A 56-year-old male with chronic hepatitis C, presenting pain in the right hypochondrium. Imaging revealed a solitary liver lesion, subsequently resected and histologically diagnosed as HCC.
Background: Disturbances in calcium and phosphorus homeostasis resulting from chronic kidney disease (CKD) may lead to atherosclerotic changes in blood vessels, potentially altering bone marrow perfusion. Our study aimed to investigate vertebral bone marrow perfusion using dynamic contrast-enhanced (DCE) MRI with a pharmacokinetic model. We also measured possible changes in water and fat content and bony trabeculae using T2* quantification, MR spectroscopy (MRS), and microcomputed tomography (μCT).

Purpose: To develop an artificial intelligence algorithm to automatically identify the anterior segment structures and assess multiple parameters of primary angle closure disease (PACD) in ultrasound biomicroscopy (UBM) images.
Design: Development and validation of an artificial intelligence algorithm for UBM images.
Methods: 2339 UBM images from 592 subjects were collected for algorithm development.
