Purpose: To investigate the role of embelin in periodontal ligament stem cells (PDLSCs) an vitro model periodontitis.Methods: Lipopolysaccharide (LPS)-stimulated PDLSCs was used to construct a periodontitis cell model. treatment group were pretreated with different concentrations Embelin, and CCK-8 TUNEL staining analyze viability apoptosis. Enzyme-linked immunosorbent assay (ELISA) kits evalua...

PURPOSE To evaluate the importance of lens epithelial cell death in age-related cataract. To determine whether the large percentage of terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL)-positive lens epithelial cells previously reported in human capsulotomy specimens results from apoptosis or necrosis. METHODS Capsulotomy specimens from patients who had underg...

The extent to which programmed cell death is the fate of proliferative, rather than post-mitotic, cells remains controversial, but a preponderance of evidence suggests that at least some cells within the brain's proliferative zone die during mammalian brain development. One major unresolved question is the extent to which cell death in the proliferative zone is spatiotemporally patterned. In or...

The growth plates of the femoral head of Japanese white rabbits aged 5, 10, 15 and 20 weeks were stained for apoptotic and proliferating chondrocytes using the TUNEL and PCNA antibody staining techniques. Both TUNEL- and PCNA-positive chondrocytes were detected in all of the specimens. The positive ratios of both stainings were calculated for the whole plate and for the resting, proliferating a...

PURPOSE The purpose of our study was to investigate alterations in the meibomian gland (MG) in Cu, Zn-Superoxide Dismutase-1 knockout (Sod1-/-) mouse. METHODS Tear function tests [Break up time (BUT) and cotton thread] and ocular vital staining test were performed on Sod1-/- male mice (n = 24) aged 10 and 50 weeks, and age and sex matched wild-type (+/+) mice (n = 25). Tear and serum samples ...

Basic fibroblast growth factor (bFGF)-loaded liposome (bFGF-lip) combined with ultrasound-targeted microbubble destruction (UTMD) technique was investigated to prevent diabetic cardiomyopathy (DCM). Cardiac function and myocardial ultrastructure were assessed. Terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) staining, immunohistochemistry staining, and Western...

P-Nonylphenol (p-NP) as a non ionic surfactant is used in many industries such as pesticides, cosmetics, detergents and so on. Our previous study showed that the p-NP causes reduction in viability of the rats Bone Marrow Mesenchymal Stem cells (MSCs). The aim of the present study was to investigate the mechanism of the cell death due to p-NP exposure. The cells, after 3 passage were treated wit...

The reliability of eight distinct methods (Giemsa staining, trypan blue exclusion, acridine orange/ethidium bromide (AO/EB) double staining for fluorescence microscopy and flow cytometry, propidium iodide (PI) staining, annexin V assay, TUNEL assay and DNA ladder) for detection and quantification of cell death (apoptosis and necrosis) was evaluated and compared. Each of these methods detects di...
