It has been shown that necroptosis-caspase-independent programmed necrotic cell death-can be induced by treatment with tumor necrosis factor (TNF) in the L929 murine fibrosarcoma cell line, even in the absence of a caspase inhibitor. Although it was reported that necrostatin-1-a specific inhibitor of necroptosis-inhibited TNF-induced necroptosis in L929 cells, it has not been elucidated whether...

Background&Aims: Themajor objective of root canal treatment is to disinfect the entire root canal system, which requires that all contents of the root canal system be eliminated as possible sources of infection. This goal may be accomplished using mechanical instrumentation and chemical irrigation. To reduce or eliminate bacteria various irrigation solutions have been applied during the treatme...

background: in this study, the effects of three structural analogues of adenosine upon proliferation of human tumor cells were investigated. previous research showed a cytotoxic effect of adenosine via a3 receptor and a1 receptor and sometimes this effect was receptor independent. the researches showed a differential cytotoxic effect of adenosine and its a3 agonists on cancerous cells, while ot...

Formocresol is common treatment in exposed pulp of primary teeth at caries, trauma and damaged with cavity preparation. Although, clinical and radiographic success and good clinical results are observed, dentistry societies are still searching for materials interchangeable with formocresol. Suab1 is a phytochemical agent that was selected because of its anti- bleeding effect. In this study, we ...

Objective (s): This study aimed at investigation of preparation and stability study of Mitomycin and Mitomycin loaded nanoliposems and efficacy of the combination of Mitomycin -loaded nanoliposomes and Curcumin versus Mitomycin in suppressing HTB-9 and L929 cell lines, in vitro.Materials and Methods: An HPLC method was validated based on Q2 (R1) International Conference on Harmonization (ICH) g...

Secretion of human soluble tumor necrosis factor receptor type I (sTNFRI) by the mouse fibrosarcoma cell line, L929, previously has been demonstrated to confer resistance to in vitro lysis by TNF and to LAK- and CTL-mediated cytolysis. These findings suggest that, in vivo, sTNFRI contributes to tumor survival by inhibiting these immunologic mechanisms. To evaluate this hypothesis, we compared t...

background: stress may cause damages to dna or/and change the ability of the cells to overcome these damages. it may also cause irregularities in the cell cycle and induce abnormal cell divisions through glucocorticoid-dependent functions. the abnormal cell divisions, in turn, lead to chromosomal mal-segregation and aneuploidy. in this study, the effects of the stress hormone, hydrocortisone (h...
