objective(s): hardystonite (ht) has been successfully prepared by a modified sol-gel method. we hypothesized thatnano-sized (ht) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size (ht).materials and methods: the hardystonite nanopowder was prepared via a modified sol-gel method.optimi...

objective(s): hardystonite (ht) is zn-modified silicate bioceramics with promising results for bone tissue regeneration. however, ht possesses no obvious apatite formation. thus, in this study we incorporated sr and ti into ht to prepare sr-ti-hardystonite (sr-ti-ht) nanocomposite and evaluated its in vitro bioactivity with the purpose of developing a more bioactive bone substitute material. ma...

background:   objective: to determine knowledge of hormone therapy (ht), reproductive physiology, and menopause in a population of 40-60 year old women.   materials and methods: this cross-sectional study was conducted through a cluster sampling among 330 women in yazd, islamic republic of iran, in 2010. data was collected using a questionnaire containing questions about reproductive physiology...

background: one of the most common endocrine problems in major beta-thalassemia is hypothyroidism (ht). the aim of this study was to evaluate thyroid function status in major beta-thalassemia patients older than 10 years old. methods: this cross sectional study was carried out on thalassemia major patients registered on thalassemia center of amirkola children hospital in babol. a questionnaire ...

Background: Hypothyroidism (HT), a relatively common condition among general population is associated with lipid profile abnormalities. The present study was designed to determine the contributive role of HT in the development of hypercholesterolemia (HCH). Methods: One hundred thirty six consecutive patients with HT and 272 euthyroid controls entered the study. Serum total cholesterol (CH) lev...

Introduction: The aim of this study was the evaluation of induced DNA damages of human prostate cancer cells, DU-145, treated with a combination of radiofrequency capacitive hyperthermia (HT) and teletherapy (EBRT) compared to a combination of teletherapy with high dose rate brachytherapy (BR).   Materials and Methods: DU-145 cells were cultured as spheroids ...

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...
