Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator of the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. The flexible redox state of iron makes it ideal to contribute in single electron transfers, but may als...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
objective(s): glioblastoma is the most lethal tumor of the central nervous system. here, we aimed to evaluate the effects of exogenous delivery of p53 and a nanoformulation of curcumin called dendrosomal curcumin (dnc), alone and in combination, on glioblastoma tumor cells. materials and methods: mtt assay was exploited to measure the viability of u87-mg cells against dnc treatment. cells were ...
objective(s):marine organisms are known as a potential source of natural products, which contain bioactive substances with therapeutic properties. sea cucumbers are prominent among marine organisms because of their dietary and therapeutic applications. in addition, they have capacity of synthesizing saponins molecules and other metabolites with therapeutic properties such as antitumor, antimicr...
background and objectives: electric, magnetic and electromagnetic fields can act as stress factors with different effects on biological systems. due to the nutritional and medicinal values, and the increasing electromagnetic radiations, the present study was performed to investigate the effects of the electromagnetic field on the developmental stages and cytotoxic properties of okra. methods: b...
background glioblastoma is a type of brain tumor with poor response to available therapies, and shows high rate of mortality. despite remarkable advancements in our knowledge about cytogenetic and pathophysiologic features of glioblastoma, current treatment strategies are mainly based on cytotoxic drugs; however, these therapeutic approaches are facing progressive failure because of the resista...
introduction: electroporation is a practical technique used to transport the molecules across the cell membrane. the utilization of fluorescent molecules is the method widely used to evaluate the electropermeability of cell membrane as a result of pulse application. it is also possible to use mathematical methods to predict the changes caused in cell electropermeability as a result of the chang...
ovarian cancer is one of the major causes of death in women. parabens are a class of chemicals widely used as preservatives in cosmetic and pharmaceutical products, they mimic estrogens, which are known to play a role in the development of different cancers in women. the aim of this study was to investigate the proliferative effects of methyl paraben (mp) and propyl paraben (pp) on human ovaria...
The neuronal microtubule-associated protein tau plays an important role in establishing cell polarity by stabilizing axonal microtubules that serve as tracks for motor-protein-driven transport processes. To investigate the role of tau in intracellular transport, we studied the effects of tau expression in stably transfected CHO cells and differentiated neuroblastoma N2a cells. Tau causes a chan...
Formononetin, an active constituent of the Chinese herb Astragali Radix, has been reported to have beneficial effects for Alzheimer's disease (AD). Yet the mechanism of this effect remains to be elucidated. The present study shows that formononetin increases soluble-AβPPα (sAβPPα) secretion and thus protects human-AβPP Swedish mutation cell (N2a-AβPP cell) from hypoxia-induced apoptosis. Using ...
