The majority of wild felids, as well as some domestic cats, have low sperm concentration in their ejaculates, and a high proportion of abnormal spermatozoa. We have employed several possible semen quality markers to further characterize cat epididymal sperm. Methods included possible apoptotic reporters, such as the annexin V assay to monitor exposure of phosphatidylserine (PS) on the outer lea...
objective: this study aimed to evaluate the incidence of apoptosis in vitrified and non-vitrified human ovarian tissue by the use of morphological analysis and apoptosis assay techniques. methods: we obtained human ovarian tissue biopsies from 30 women who underwent elective caesarean sections. tissues were transported to the laboratory in pre-warmed, equilibrated leibovitz l-15 medium within 2...
Apoptosis is an important mode of cell death under both physiological and pathophysiological conditions. Numerous techniques are available for the study and quantitation of apoptosis in cell culture, but only few are useful when applied to complex tissues. Among these, the terminal transferase-mediated dUTP nick end-labeling (TUNEL) assay remains the most widely used technique. However, its spe...
Proteinak polimero lineal gisa sintetizatzen dira eta beren jatorrizko egitura tridimentsionalean tolestu behar zelulan hainbat funtzio betetzeko. Proteinen tolespena ulertzea funtsezkoa da, tolespen okerrak gaixotasun neuro-degeneratiboren jatorria direlako. modu koitzultzailean has daiteke, hau sortzen ari den peptidoa erribosomari lotuta dagoenean oraindik. Izan ere, zelularen proteinen here...
Abstract At present, nuclear condensation and fragmentation have been estimated also using Hoechst probes in fluorescence microscopy flow cytometry. However, none of the methods used for quantitative spectrofluorometric assessment. Therefore, aim present study was to develop a assay detection intact cells. We human hepatoma HepG2 renal HK-2 cells cultured 96-well plates treated with potent apop...
Introduction: Repetitive cortical spreading depression (CSD) can lead to cell death in immature brain tissue. Caspases are involved in neuronal cell death in several CSD-related neurological disorders. Yet, whether repetitive CSD itself can induce caspase activation in adult or juvenile tissue remains unknown. Inducing repetitive CSD in somatosensory cortices of juvenile and adult rats in vivo,...
In this study, the cytotoxic effects of aqueous and ethanolic extracts of Sedum album L. on human stomach cancer cell line (AGS) and breast cancer cell line (MCF-7) were evaluated by MTT, BrdU and TUNEL assays. The results demonstrated that both extracts had antiproliferative and apoptotic effects in a dose-dependent manner. The MTT assay data revealed that the AGS cell underwent more cytotoxic...
