This study aimed to synthesize two new fluorescent narrow rim-functionalized 4-sulfo-1,8-naphthalimide derivatives of calix[4]arenes (4 and 7) examination their cytotoxic properties for cancerous cells. For this purpose, p-tert-butylcalix[4]arene bearing dihydrazide (3) or diaminopropyl (6) units on its rim were reacted with 4-sulfo-1,8-naphthalic anhydrate. The IC50 values 4 7 determined as 12...

The effects of cAMP-analogue dibutyryl-cAMP and anticalmodulin W-7 were studied on de novo synthesis and secretion of lipids in cultures of hepatoma McArdle RH7777 cells and normal rat hepatocytes. Dibutyryl-cAMP and W -7 separately caused a significant decrease in the secretion of de novo synthesized triacyl [3H]glycerol in both cultures of McArdle cells and rat hepatocytes. The inhibito...

Backgrounds: Evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. For the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. However, the role of the tissue architecture was neglected. Three dimensional (3D) cell cultures which can recap...

Introduction: By relying on polymorphonuclear (PMN) cells, stromal vascular fraction (SVF) and platelet-rich plasma (PRP) contribute significantly in the healing process. Through anal trauma model, this study examined effect of SVF PRP combination PMN counts vivo. Method: Three groups twenty-eight eligible Wistar rats model randomly assigned to receive (Group A), normal saline B), or healthy co...

Objective(s):Valproic acid (VPA), a drug used in the treatment of neurological disorders, has been shown to have cytotoxic effects on cancer cells through different mechanisms. Telomerase, a ribonucleoprotein reverse transcriptase, is responsible for elongation of the telomere and is activated in cancers. A relation between telomerase activity and resistance to apoptosis has been established. T...

      ICD-85 (venom derived peptides) has anti-proliferative effect and anti-angiogenesis activity on cancer cells. This study was performed to test the effect of ICD-85, on Human breast adenocarcinoma (MCF-7) and normal Human Dermal Fibroblasts (HDF) cell lines. In this experimental study, Mitochondrial activity, Neutral red uptake, Lactate dehydrogenase (cell necrosis), and cell morphology we...
