Background: Plants are a proven source of anti-tumor compounds and it is reasonable to assume that many such substances remain to be discovered. In Iranian folk medicine, ethanolic extract of the aerial parts of Daphne mucronata Royle is used against various skin disorders.Objective: In order to evaluate anti-neoplastic plants, we initiated a cytotoxic study using Daphne mucronata that is indig...

background: metformin is used to lower blood sugar in patients with type ii diabetes. recent research showed that metformin has effects on cancer cell growth. studies show that metformin can induce apoptosis in certain cancer cell lines. in this study, we examined the effect of metformin on apoptosis in the t47d breast cancer cell line. methods : the t47d breast cancer cell line was selected an...

conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...

Since Coxeter’s work [3], the 24-cell is known for its nice combinatorial and geometric structure in the Euclidean sense. We demonstrate that it possesses optimal properties I and II in the hyperbolic setting. Question I is closely related to the volume spectrum of four-dimensional hyperbolic manifolds [10], question II is new and is both of combinatorial and geometric nature. Furthermore, usin...

The clinical presentation, differential diagnosis, and etiologic factors for basal cell carcinoma and squamous cell carcinoma were detailed in Chapter 19. This chapter defines the treatment modalities that are effective in extirpating cutaneous basal cell and squamous cell carcinomas, including electrosurgery, excisional surgery, cryosurgery, irradiation, and Mohs surgery. The last technique, a...

Cardiomyocyte cell death is a major contributing factor to various cardiovascular diseases and is therefore an important target for the design of therapeutic strategies. More recently, stem cell therapies, such as transplantation of embryonic or induced pluripotent stem (iPS) cell-derived cardiomyocytes, have emerged as a promising alternative therapeutic avenue to treating cardiovascular disea...

Pancreatic ductal adenocarcinoma is one of the most deadly forms of cancers, with a mortality that is almost identical to incidence. The inability to predict, detect or diagnose the disease early and its resistance to all current treatment modalities but surgery are the prime challenges to changing the devastating prognosis. Also, relatively little is known about pancreatic carcinogenesis. In o...

The secosteroid hormone 1alpha,25-dihydroxyvitamin D3 [1,25-(OH)2D3] has potent antiproliferative and prodifferentiating actions on a wide variety of normal as well as malignant cell types. Strong calcemic effects obstruct the actual application of 1,25-(OH)2D3 for the treatment of hyperproliferative disorders such as cancer. To overcome this problem, structural analogs of 1,25-(OH)2D3 have bee...

introduction: cardiac glycosides such as digoxin or digitoxin are the natural products that are traditionally used to increase cardiac contractile force in patients with heart failure and cardiac arrhythmias. it has been shown that digoxin can directly inhibit the cell proliferation and lead to cell apoptosis. present study was conducted to analyze the effect of digoxin in the cohorts of mesenc...
