Aspiration biopsy specimens were taken from malignant tumours--1 Hodgkin's lymphoma, 3 non-Hodgkin lymphomas, 1 squamous cell carcinoma and 1 adenocarcinoma-before and after irradiation. Individual cells were analysed by micro-electrophoresis, a new technique which estimates radiation-induced DNA strand breaks. The cells were embedded in agarose gel; after lysis of the cells in a neutral detergent solution, an electric field (5 V/cm) was applied for five minutes. DNA showed a tendency to migrate, some cell diameters, and was more pronounced in irradiated than in control cells. The DNA migration was evaluated by a microscope photometer which estimated the fluorescence in cells stained with acridine orange. This technique was found to be suitable for human material in vivo as only a few cells are needed and no radioactive prelabelling is necessary.

Clonal hematopoiesis of indeterminate potential (CHIP) is a condition where blood or bone marrow cells carry mutations associated with hematological malignancies. Individuals with CHIP have an increased risk of developing hematological malignancies, atherosclerotic cardiovascular disease, and all-cause mortality. Bone marrow transplantation (BMT) of cells carrying CHIP mutations into irradiated mice are useful procedures to investigate the dynamics of clonal expansion and potential therapeutic strategies, but myeloablative conditioning can induce confounding effects.

Over recent years, the retina has been increasingly investigated as a potential biomarker for dementia. A number of studies have looked at the effect of Alzheimer's disease (AD) pathology on the retina and the associations of AD with visual deficits. However, while OCT-A has been explored as a biomarker of cerebral small vessel disease (cSVD), studies identifying the specific retinal changes and mechanisms associated with cSVD are lacking.

Background: Transarterial chemoembolization (TACE) is the first-line therapeutic option for patients with intermediate-stage hepatocellular carcinoma (HCC). Tumor neovascularization allows tumor growth and may facilitate the release of circulating tumor cells (CTCs) to the bloodstream after TACE. We investigated the relationship between early release of CTCs and radiological response after TACE.

Extracellular vesicles (EVs) are taken up by most cells, however specific or preferential cell targeting remains a hurdle. This study aims to develop an EV that targets cells involved in inflammation, specifically those expressing intercellular adhesion molecule-1 (ICAM-1). To target these cells, we overexpress the ICAM-1 binding receptor "lymphocyte function-associated antigen-1" (LFA-1) in HEK293F cells, by sequential transfection of plasmids of the two LFA-1 subunits, ITGAL and ITGB2 (CD11a and CD18).
