ABSTRACT
The aim of this study was to evaluate and compare the relationship between body image and quality of life in female patients with breast cancer and healthy women. In the current descriptive, causal, comparative, cross-sectional study, 50 women with breast cancer, referring to the radiotherapy and oncology clinic of Imam Reza Hospital [Mashhad, Iran] and 50 healthy women, referring to the same clinic, were selected via available sampling. Informed consent forms were obtained from the subjects. A demographic questionnaire, Multidimensional Body-Self Relations Questionnaire [consisting of 46 items], and short-form health survey [SF-36] were used as the study tools. For data analysis, Pearson's correlation test and t-test were performed to determine the differences between the two groups. Data were analyzed, using SPSS version 16. The results showed a statistically significant difference between female patients with cancer and healthy women in terms of quality of life [t=-4.1, P<0.001]. Moreover, a significant direct relation was found between body image [and its components] and quality of life [and its components]. The current findings suggest a significant difference between healthy and cancer-stricken women in terms of quality of life and body image. Also, higher scores of body image in cancer patients were associated with higher quality of life
ABSTRACT
Acrylic base resins are widely used in orthopedics and dental surgery. It is generally accepted that due to the incomplete conversion of methyl methacrylate [MMA] monomer to the polymer form during polymerization of the resin, some MMA monomers remain in the hardened material. MMA monomer has been reported to cause abnormalities or lesions in several organs of animals. Study of the literatures showed that there are no perfect and valid methods for analysis of MMA. The aim of this study was to develop a simple and valid method for determination of MMA residual monomer in the denture base resins. We have developed and validated an analytical procedure employing gas chromatography with flame ionization detector [GC-FID], with temperature programming, and a close analogue internal standard for fast and repeatable analysis of MMA residual monomer contents in denture base polymers. For quantification of monomer, two calibration curves were used by two different methods of solution preparation and they were compared to each other. The assay was linear over the range of 0.03-0.6 mg/ml MMA with correlation coefficients [r[2]] of greater than 0.99. Accuracy, intra-day [Error<9.1%] and inter-day [Error<6.6%], precision [RSD<5.5% and RSD<6.5%, respectively] were in acceptable values over the examined concentration range. Limit of detection [LOD] and limit of Quantification [LOQ] for MMA were 0.01 and 0.02 mg/ml, respectively. In conclusion, the proposed method was a simple and fast assay for MMA residual monomer in denture base resins
