Published: December 2024

Medin is a protein fragment derived from milk fat globule epidermal growth factor VIII (MFG-E8). Medin aggregates are present in the vessel wall of most subjects over 50 years of age. In this narrative review, we focus on the consequences of medin aggregation in relation to the development of dementia. Recent literature revealed medin as biomarker for dementia in CSF, specifically of a vascular subtype. Preclinical work showed that medin is associated with aging-related cerebral vascular dysfunction, vascular stiffening, hypertension, and. vascular amyloid β deposition. These findings position medin as a potential mechanistic link between aging, vascular pathology and dementia.

Objective: In advanced ovarian cancer, the majority of patients receive anti-angiogenic treatment with bevacizumab. However, its use is often associated with severe side effects, and not all patients benefit from the therapy. Currently, there are no reliable biomarkers to predict response to treatment.

In non-papillary follicular cell-derived thyroid carcinomas, prognostic factors are scarce. Intratumoral fibrosis was identified as an adverse factor in papillary and medullary carcinomas, but it has not been investigated in other subtypes. We aimed at exploring the presence of intratumoral fibrosclerosis in a cohort of 132 non-papillary follicular cell-derived thyroid carcinomas (53 follicular and 31 oncocytic carcinomas, including 10 high grade differentiated thyroid carcinomas and 48 poorly differentiated carcinomas) and correlating its presence and extent with clinical and pathological features and survival.

Role of macrophage in intervertebral disc degeneration.

Bone Res

Department of Spine Surgery, Tianjin Hospital, Tianjin University, Tianjin, 300211, China.

Intervertebral disc degeneration is a degenerative disease where inflammation and immune responses play significant roles. Macrophages, as key immune cells, critically regulate inflammation through polarization into different phenotypes. In recent years, the role of macrophages in inflammation-related degenerative diseases, such as intervertebral disc degeneration, has been increasingly recognized.

This case revolves around a mid-childhood boy diagnosed with a chemoresistant chondroblastic osteosarcoma, a rare and aggressive form of bone tumour affecting his left proximal humerus. Histopathological confirmation of chondroblastic osteosarcoma was obtained through core-needle biopsy. Despite initiating cytoreductive neoadjuvant chemotherapy using a vincristine and cyclophosphamide regimen, the tumour exhibited resistance, prompting the decision to proceed with a forequarter amputation.

Exploring the impact of nano platinum-hydrogen saline on oxygen-induced retinopathy in neonatal rats.

J Matern Fetal Neonatal Med

December 2025

Department of Pediatrics, Traditional Chinese and Western Medicine Hospital of Wuhan, Tongji Medical College, Huazhong University of Science and Technology, Wuhan No.1 Hospital, Wuhan, China.

Objective: The objective of this study is to assess the impact of nano platinum-hydrogen saline (Pt NPs + H) on oxygen-induced retinopathy (OIR) in neonatal rats, with the goal to contribute new insights into the therapeutic strategies for retinopathy of prematurity.

Methods: Pt NPs + H formulation was synthesized to address OIR in a rat model. Subsequent examination included the assessment of retinal blood vessel distribution and morphology through hematoxylin and eosin (HE) and isolectin B4 (IB4) staining techniques.
