conclusions due to the significant reduction in the mean inactivation dose of colon cancer cells in the presence of gold nanoparticles, it seems that gnps are suitable options to achieve a new approach in order to improve radiotherapy efficiency without increasing the prescribed radiation dose. results cell survival in the presence of gnps was more than 90% and the maximum uptake of gnps was ob...
Background and purpose: Acute leukemia is a malignancy with a rapidly progressive course of the lymphoid or myeloid cells. A prognostic factor for its survival and treatment is of particular importance in medical research. Therefore, this study aimed at applying competing risk model to compare clinical and pathologic factors in pediatric acute leukemia. Materials and methods: A historical coho...
this study was intended to investigate the effectiveness of static magnetic field on the growth of escherichia coli (e. coli) provided from two sources, the urine samples of patients with urinary tract infections and the reference strain e. coli atcc 25922. bacterial samples in nutrient broth were subjected to a range of magnetic intensities (2, 4, 6, 9, 14, 16, 18, and 20 mt) at various exposu...
to survive in natural waters, bacteria must respond to variety of environmental factors. flexibacter survival in the aquatic environment is influenced by number of parameters, such as temperature, heavy metal concentration and oxidation. here we investigate the influence of these factors on the survival of flexibacter chinensis in starvation medium. our data shows that different concentrations ...
Background and Objective: In neurodegenerative disorders, oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages that lead to apoptosis. Pro-apoptotic and anti-apoptotic gene expressions were changed during cell differentiation that affect cell viability and differentiation. This study was conducted to determine the effects of hydrogen peroxi...
Background and purpose: Recently studies have shown that main compound (Cyclotides) of Viola odorata has an inhibitory effect against proliferation of cancer cells. Also, melatonin reduces size and growth of tumor cells. The main purpose of this study was to compare the inhibitory effect of Viola odorata and melatonin on MDA-MB-468 cells proliferation. Materials and methods: In this exprimental...
Background and purpose: Because of theirmultipotency and ease of purification, amplification and immunomodulatory properties Mesenchymal stem cells (MSC), are anideal stem cell source for cell therapies. This study was done to investigat the effect of Rat MSCs on the survival neutrophils. Materials and methods: MSCs was isolated from rat (6-8 weeks) femoral and tibial bone marrow and cultu...
Objective(s): Apoptotic effect of apoptin has been demonstrated in numerous studies. However, its tumor specificity has been questioned by some reports. The aim of this study was to confine the expression of apoptin in the prostate tumor cells by inducing its gene expression under the control of a chimeric enhancer composing of prostate-specific membrane antigen (PSMA) and prostate-specific ant...
An unbounded number of events exist beneath the intricacy of each particular hematologic malignancy, prompting the tumor cells into an unrestrained proliferation and invasion. Aberrant expression of cyclin-dependent kinases (CDKs) is one of these events which disrupts regulation of cell cycle and subsequently, results in cancer progression. In this study, we surveyed the repressive impact of mu...
Background: the aim of this study was to investigate the prognostic value of 18Fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) parameters in both overall survival and progression-free survival in Stage I-III non-small cell lung cancer (NSCLC). Materials and Methods: In this retrospective study, 267 patients who were diagnosed as Stage I-III non-smal...
