Unscheduled DNA synthesis after partial UV irradiation of the cell nucleus [PDF]

, 1979
Cells of an euploid strain of the Chinese hamster synchronized in the G1 phase were microirradiated in the nucleus with a laser UV microbeam (λ = 257 nm) and pulse-labelled with [3H]thymidine. In autoradiographs of cells fixed immediately after the pulse

Perspectives in Microvascular Fluid Handling: Does the Distribution of Coagulation Factors in Human Myocardium Comply with Plasma Extravasation in Venular Coronary Segments? [PDF]

, 2010
Background: Heterogeneity of vascular permeability has been suggested for the coronary system. Whereas arteriolar and capillary segments are tight, plasma proteins pass readily into the interstitial space at venular sites.

Albumin-heparin microspheres as carriers for cytostatic agents [PDF]

, 1990
Much work has been done on adriamycin-loaded albumin microspheres (Alb-MS) for chemoembolization [1–4], the rationale being that site-specific drug delivery may increase the therapeutic efficacy of the drug. Alb-Ms are being investigated because of their

A Solid Dispersion of Quercetin Shows Enhanced Nrf2 Activation and Protective Effects against Oxidative Injury in a Mouse Model of Dry Age‐Related Macular Degeneration

Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Age‐related macular degeneration (AMD) represents a major reason for blindness in the elderly population. Oxidative stress is a predominant factor in the pathology of AMD. We previously evaluated the effects of phospholipid complex of quercetin (Q‐PC) on oxidative injury in ARPE‐19 cells, but the underlying mechanisms are not fully understood.
