background: despite the outbreak in dental science, oral and dental complications in alzheimer are of the unsolved problems. it is assumed that tumor necrosis factor-α, which is a key factor in alzheimer, has a relation with periodontal complications in patients with alzheimer disease. the present study evaluated the effect of chronic periodontitis on serum levels of tumor necrosis factor-α in ...

introduction: as a physical treatment, electrochemical therapy (echt) has provided an effective and useful  approach  for  treating  localized  tumors.  the  chemical  changes  due  to  a  direct  electric  current  destroy  the  tumor. this study evaluates the effect of electrical dose and polarity on the efficacy of the treatment of a  colon tumor model.  materials and methods: in order to in...

Realgar, a traditional Chinese medicine, has notable antitumor activity and can be used in various hematologic tumor solid therapies wide range of clinical applications. Nanosized realgar possesses higher surface enhanced therapeutic effects on cancer cells compared with those bulk realgar. In this study, we reported the design high-performance nanorealgar quantum dots (NR QDs) aggregation-indu...

Background: Artemisia diffusa contains a new type of sesquiterpene lactone with an endoperoxide group (Tehranolide). Objective: Due to the existing similarity between the structures of Tehranolide and Artemisinin, it was hypothesized that Tehranolide would have similar effects as Artemisinin. In this study, the immunotherapeutic effec-tiveness of Tehranolide was investigated by direct intra-tum...

Prognosis of metastatic breast cancer is very poor which urges the necessity to develop novel potential drug candidates. We assessed two compounds with tri-aryl structures (A and B) for their potency to reduce primary breast tumor growth and lung metastasis in 4T1 mice model. MTT assay, 4T1 mammary mouse model and immunohistochemistry experiments were used in this study. In vitro results exhibi...

It has recently been observed that the incidence of liver tumors due to p-dimethylaminoazobenzene is much less in rats fed a diet deficient in pyridoxine than in animals on a more complete ration (6). The effect of pyridoxine was evident when the caloric intake of the animals on the two diets was equal, and no similar effect was observed in any of a number of other vitamin deficiencies. Several...

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...
