Objective: To study the feasibility of using combined morphology and terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick-end labeling (TUNEL) for apoptosis detection and the impact of cryopreservation on this process. Materials and methods: We conducted this investigation using a porcine animal model. Bilateral oophorectomy was performed in eight sows. The ovarian tissues were ...
A mouse jejunum, when incubated in vitro in Ussing chambers, was found to exhibit morphological deterioration of the villi with denudation of the epithelia (J Nutr Sci Vitaminol, 51: 406, 2005). Our study examined the involvement of apoptosis in an intestinal injury model by a DNA ladder assay and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay. Electrophores...
To accurately quantify the number of single-strand breaks (SSBs) induced in plasmid DNA molecules after irradiation, a new type of assay methodology has been explored. The new method is based on the TUNEL (terminal deoxynucleotide transferase dUTP nick end-labeling) assay that was adopted for use under ELISA (enzyme-linked immunosorbent assay) conditions. The assay was found to both improve the...
We have examined the development of rat striatum for evidence of cells dying in the process of physiological cell death. In present study we have indicated apoptotic cells in sections stained with cresyl violet (cell death characterized by pyknosis) or with DNA end labeling assay (TUNEL method). Our results demonstrated that cell loss during maturation of the rat striatum had the characteristic...
Aim The aim of this study was to examine the potential ameliorative effects caffeic acid (CA) on hydrogen peroxide (H2O2)-induced neurodegeneration in a human SH-SY5Y cell line, as well possible mechanisms involved. Method Cell proliferation evaluated by WST-1 assay. apoptotic index calculated TUNEL Assay. Antioxidant parameters were studied measuring reactive oxygen species (ROS), lipid peroxi...
Background: In mammalian ovaries, loss of over two-thirds of germ cells happens due to cell death. Nonetheless, the exact mechanism of cell death has yet to be determined. The present basic practical study was designed to detect 3 types of programmed cell death, namely apoptosis, autophagy, and necrosis, in murine embryonic gonadal ridges and neonatal ovaries.Methods: Twenty gonadal ridges and ...
DIHS/DRESS is a severe adverse drug reaction characterized by persistent eruption associated with reactivation of herpesviruses. In acute phase the disease, purpura occasionally observed mainly in limbs. We recently demonstrated that area lower limbs correlates severity as assessed score. However, pathogenesis has not been examined. collected four patients DIHS and two erythema multiforme (EM)....
BACKGROUND/AIM It is known that trypan blue staining is not a good predictor of loss of corneal endothelial cells (ECs) during organ culture. As it is primarily an indicator of membrane integrity, it would also not be expected to identify ECs undergoing apoptosis. The aim of this study was to determine the ability of the in situ TdT dUTP mediated nick end labelling (TUNEL) technique to detect c...
