Objectives: The purpose of this investigation was to examine the association between endometrial cancer and possible etiological agents. Methods: A case-control study was conducted in Iran between March 2012 and May 2016. The demographic and reproductive factors of 205 women with endometrial cancer were compared, and 590 healthy cases were participated in the control group. For each endometrial cancer case, there were three controls, who were matched in terms of age and residence. The data were considered significant at $p{\leq}0.05$. Results: After adjusting the variables, the nulliparity (OR 6.23, 95% CI 2.86-13.59), the nulligravidity (OR 5.94, 95% CI 2.51-14.06), the positive family history of reproductive cancer (OR 4.97, 95% CI 2.33-10.59), the infertility history (OR 2.38, 95%CI 1.32-4.31), the obesity ($BMI{\geq}25$) (OR 1.71, 95% CI 1.16-2.52), the early menarche age (<12 years) (OR 2.10, 95% CI 1.17-3.75), and the hormonal contraception use (OR 1.69, 95% CI 1.15-2.49) were found to be associated with an increased risk of endometrial cancer. Nevertheless, the education level, the job of women, the marital age, the leisure activities, and the breast feeding were not found to be associated with the endometrial cancer after adjusting the variables. Conclusion: Scheduling of the screening program is vitally indispensable to identify endometrial cancer in women with nulliparity, nulligravidity and the positive family history of cancer. In addition, women with early menarche, those with the history of infertility, the obese ones, and those who use contraception pills need to be particularly aware of the potential risks.

Hypoxia inducible factor $1\alpha$ (HIF-$1\alpha$) is a potential marker of carcicnogenesis since it is overexpresssed in many human cancers such as brain, breast, and uterus, and its role has implicated in tumor cell growth and metastasis. In this study, we established a stable cell line that express green fluorescence protein (GFP)-fused hypoxia inducible factor $1\alpha$ (HIF-$1\alpha$) and evaluated the potential use of this cell line for assessment of carcinogenicity of chemical toxicants. Western blot analysis as well as fluorescence measurements showed that protein-level of GFP-HIF-$1\alpha$ was significantly enhanced in a dose-dependent manner upon treatment of hypoxia mimicking agents such as dexferrioxamine and $CoCl_2$. Well-Known tumor promoters such as mitomycin and methyl methanesulfonate. significantly induced the fluorescence intensity of GFP-HIF-$1\alpha$, whereas the known negative controls such as o-anthranilic acid and benzethonium chloride, did not. These results indicate that HIF-$1\alpha$ could be a biological parameter for detection of tumor initiators/promoters and suggest that the GFP-HIF-$1\alpha$ cell line is a useful system for screening of carcinogenic toxicants.

Purpose: The purpose of this study was to develop child's health assessment tools and tailored home visiting nursing service model in a community. Methods: Based on the literature review and several types of workshops participated with the child health nursing professors and visiting nurses in public health centers from May to December 2009, the standards of child health assessment tools, service model and education materials for visiting nurses were developed. Results: Some record forms were newly developed, including neonatal assessment, breast feeding, mother-infant interaction, oral care, vaccination and safety, and appropriate developmental screening tests in the community were selected. For systematic health care management in the community, problem list, problem criteria, health care plan, outcome criteria were also developed. Conclusion: On the demand of growing need for health promotion and early intervention for children and their association with parenting and socioeconomic status, assessment and control measures are indispensable to the promotion of child health for vulnerable population. Children's health and developmental problems, and safe circumstances can be assessed using this assessment tools, and can be used for tailored home visiting nursing care for children.
Exposures to environmental chemicals that mimic endogenous hormones are proposed for a number of adverse health effects, including infertility, abnormal prenatal and childhood development and above all cancers. In addition, recently miRNA (micro RNA) has been recognized to play an important role in various diseases and in cellular and molecular responses to toxicants. In this study, endocrine disrupting environmental toxicant, nonylphenol (NP) was treated to MCF-7 (Human breast cancer cell) and HepG2 (Human hepatocellular liver carcinoma) cell line at 3 hrs and 48 hrs time point and miRNA analysis using $mirVana^{TM}$ miRNA bioarray was performed and compared with total mRNA microarray data for the same cell line and treatment. Robust data quality was achieved through the use of dye-swap. Analysis of microarray data identifies a total of 20 and 11 miRNA expressions at 3 hrs and 48 hrs exposure to NP in MCF-7 cell line and a total of 14 and 47 miRNA expression at 3 hrs and 48 hrs exposure respectively to NP in HepG2 cell line. Expression profiling of the selected miRNA (let-7c, miR-16, miR-195, miR-200b, miR200c, miR-205, and miR-589) reveals changes in the expression of target genes related to metabolism, immune response, apoptosis, and cell differentiation. The present study can be informative and helpful to understand the role of miRNA in molecular mechanism of chemical toxicity and their influence on hormone dependent disease. Also this study may prove to be a valuable tool for screening potential estrogen mimicking pollutants in the environment.
Discovery of anticancer drugs that kill or disable tumor cells in the presence of normal cells without undue toxicity is a potential challenge for therapeutic care. Several papers in the literature have emphasized the potential implications of marine products such as seaweeds which exhibit antitumor activity. Study attempts to screen the antitumor effect of Sargassum sp, against chosen cell lines such as MCF-7 (Breast cancer) and Hep-2 (Liver Cancer). Ethanol extract of Sargassum sp. was concentrated using a Soxhlet apparatus and dissolved in DMSO. In vitro cytotoxic activity of Sargassum sp at various concentrations ($100{\mu}g/ml-300{\mu}g/ml$) screened for antitumor effect against the chosen cell lines using MTT assay (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide, a yellow tetrazole). The study documented that the percentage of cell viability has been reduced with increased concentration, as evidenced by cell death. Sargassum sp extract shows potential cytotoxic activity ($P{\leq}0.05$) with $IC_{50}$ of $200{\mu}g/ml$ and $250{\mu}g/ml$ against Hep-2 and MCF-7 cell lines respectively. The ethanol fraction of Sargassum sp induced cell shrinkage, cell membrane blebbing and formation of apoptotic bodies with evidence of bioactive components as profound influencing factors for anti-tumor effects. Further research need to be explored for the successful application of Sargassum sp as a potent therapeutic tool against cancer.
The purpose of this study was to identify transition conditions, health behavior and indicators of healthy transitions among middle-aged women based on Schumacher & Meleis(1994) transition model for developing intervention program for their health promotion. A convenience sample of 221 women aged 40-60 was obtained in Jung-Gu, Seoul and they were asked to complete the questionnaires, which consisted of modified health-promoting lifestyle profile(HPLP), knowledge of menopause, physical well-being, emotional well-being, modified women's role integration protocol (WRIP), Beck's Depression Inventory(BDI), and indicators of healthy transition with subcategories such as subjective well-being, role mastery and well-being of interrelationship. The results were as follows: 1. Women had a mean age of 47.53 years. More than half(53.39%) of the women had jobs and 88.69 % had their spouses, Of 221 women, 51.13 % were premenopausal, 19.91% were perimenopausal, and 28.96% were postmenopausal. 2. Women scored lower on health responsibility and exercise than on self actualization, nutrition and interpersonal support among subcategories of health behavior measured the modified HPLP. Only 11.98% of respondents had breast-self examination and 42.66% had pap smear for screening cancer. 3. In transition conditions, women had poor knowledge about menopause and median level of physical well-being, emotional well-being and stress. 15.45% of the women had clinical depression. 4. As for the outcome index of the transition model, the mean of indicators of healthy transition was 3.69(possible range 1-5). 5. The levels of education and economic and the menstrual status were significantly related to physical well-being, depression and stress in the categories of transition conditions. The total score of health behavior correlated negatively with depression. The total score of indicators of healthy transition correlated with physical well-being, emotional well-being, stress, and depression in the categories of transition conditions. In conclusion, these findings suggested a profile of fragile middle-aged women and contributed to developing the community-based intervention program for health promotion.

Presently, the world population of the elderly is growing. By improving health hygiene and welfare indicators, mortality and birth rates decrease and life expectancy increases, making the present century the century of elderly. Aging is one of the main risk factors for development of cancer, which itself is the second cause of death in old people. This study was conducted to assess the prevalence of cancer in the elderly covered by the Islamic Republic of Iran Broadcasting (IRIB) insurance program and to obtain suitable programs for cancer screening and early detection, increase patient survival, improve elderly care and to reclaim the cost of treatment in comparison to the national and international statistics. This is a cross-sectional study conducted on all elderly patients diagnosed with malignancy based on their pathology reports. In this study, of the total 75,500 patients covered by IRIB insurance, 17.2% belonged to the elderly group, males accounting for 53.3%. The most common cancers in old men were prostatic cancer (61.3%), colon cancer (10.3%) cancer of the hematologic system, bladder cancer (9.6%), lung cancer (9.1%), thyroid cancer (3.9%) and brain tumors (1.3%). In the elderly women, the most common cancers were breast cancer (80.1%), colon cancer (5.1%), thyroid cancers (4.4%), bladder and hematologic system malignancies (3.6), lung cancer (2.9%) and brain tumors (0.7%). In addition, the prevalence of cancer was almost the same as national and international statistics. With the exception of non-melanoma skin cancer no difference was shown in prevalence of cancer between IRIB elderly patients and the other groups of cancer patients in Iran.
Background: According to increase in elderly populations, and change in lifestyle and cancer-causing behavior, the global burden of cancer is increasing. For prevention and control of disease, knowledge of population statistics of cancers and their trends is essential. This study aimed to investigate the epidemiology and trends of cancer in the province of Kerman: southeast of Iran. Materials and Methods: This analytical and cross-sectional study was carried out based on cancer registry data at the Disease Management Center of the Health Ministry from 2004 to 2009 in the province of Kerman in Iran. Common cancers were defined as the number of reported cases and standardized incidence rates. To compute the annual percentage change (APC), joinpoint 4.1.1.1 software was applied. Results: Of 10,595 registered cases, 45.3% (4802 cases) were in women and 56.7% (5,793 cases) occurred in men. The standardized incidence rates for both females and males were increasing during the six years studied. The most common cancers in both sexes during six years of studied were skin (13.4%), breast (9.35%), bladder (7.8%), stomach (7.45%), leukemia (7.05%), colorectal(5.57%), lung(4.92%), trachea(3.51%) and prostate(2.48%). Conclusions: Our findings revealed that the cancer incidence is demonstrating increasing trends in both sexes in the province of Kerman. This may be because of changes in lifestyle, increasing exposure to risk factors for cancer and increase of life expectancy. If this is the case, increasing public awareness of cancer risk factors is a high priority, together with introduction of large-scale screening techniques.
The primary objective of these studies was to screen the materials showing inhibitions of HMG-CoA reductase in vitro. The secondary objective was to determine the effect of garlic, lovastatin and copper on cholesterol concentrations in plasma. liver and brease muscle of pullets. In experiment 1, the degree of inhibition of the selective samples on HMG-CoA reductase activity was determined in vitro. The inhibition rate of water soluble garlic extracts, lovastatin and copper to HMG-coA reductase activity were 51.3%, 87.5%, and 82.0% respectively . In experiment 2, control diet (basal diet), garlic powder (3% in diet) , lovastatin (300mg/kg of diet) and copper(200mg/kg of diet) were fed to pullets in order to investigate the changes of cholesterol concentration in plasma and tissues. Plasma total cholesterol , and LDL-cholesterol were significantly reduced in pullets fed a diet containing 3 % garlic powder. However, coper significantly increased total cholesterol compared to controls and lovastatin did not affect plasma chholesterol concentration . Total cholesterol inlover and breast muscle inpullets were not affectedb y adding cholesterol lowering materials to the diets. The data suggests that it is not easy for HMG-CoA reductase inhibitors to reduce cholesterol levels in the body due to complication in cholestrol metabolism . However, garlic administration can lower the levels of plasma cholesterol in pullets.

Although it is well known that cancer patients suffer from malnutrition, there are few published studies on malnutrition in outpatients receiving chemotherapy in Korea. This study aimed to evaluate nutritional risk in oncology outpatients receiving chemotherapy and to show the baseline data to set up nutritional management programs for cancer patients. This is a retrospective observational analysis on 1,962 patients referred for nutritional education before or during chemotherapy at Seoul National University Hospital Cancer Center from January 2006 to May 2007. According to a malnutrition screening tool, the proportion of patients having malnutrition risk was 23.0%. In the case of upper gastrointestinal cancer, more than 50% of patients were assessed as being at the risk of malnutrition. They showed more than 7% weight loss compared to their usual body weight and poor oral intake; energy intake was less than 100% of Basal Energy Expenditure(BEE) and protein intake was less than or equal to 0.77 g/kg/d. However, only 6.3% of breast cancer patients had risk of malnutrition and their oral intake was better; energy intake was 121% of BEE, and protein intake was 0.90 g/kg/d. Outpatients receiving chemotherapy had different nutritional risk depending on their cancer site. Nutritional management program should be conducted differently, depending on the cancer site and upper gastrointestinal cancer patients at high risk of malnutrition should basically have nutritional assessment and intervention.
