This is the first comprehensive cohort study of the health of older people ever conducted in Iran. The aim of this project is to investigate the health status of older people in Amirkola in the northern part of Iran, near the Caspian Sea. The Amirkola Health and Ageing Project (AHAP) is mainly concerned with geriatric medical problems, such as falling, bone fragility and fractures, cognitive impairment and dementia, poor mobility and functional dependence. It is planned that all participants will be re-examined after 2 years. Data are collected via questionnaire, examinations and venepuncture. AHAP started in April 2011 and 1616 participants had been seen by 18 July 2012, the end of the baseline stage of this study. The participation rate was 72.3%. The prevalence of self-reported hypertension (41.2%) and diabetes mellitus (23.3%) are high. Only 14.4% of older people considered their health as excellent or good in comparison with others at this age. The prevalence of osteoporosis (T score≤-2.5) was 57.4% in women and 16.1% in men, and 38.2 % of older people were vitamin D deficient (<20 ng/ml). Researchers interested in using the information are invited to contact the principal investigator Seyed Reza Hosseini (hosseinim46@yahoo.com).

Breast cancer is the most prevalent cancer and one of the leading causes of death among women in the world. Plants and herbs may play an important role in complementary or alternative treatment. The aim of this study was to evaluate the antioxidant and anti-proliferative potential of Urtica dioica. The anti oxidant activity of an aqueous extract of Urtica dioica leaf was measured by MTT assay and the FRAP method while its anti-proliferative activity on the human breast cancer cell line (MCF-7) and fibroblasts isolated from foreskin tissue was evaluated using MTT assay. Mechanisms leading to apoptosis were also investigated at the molecular level by measuring the amount of anti and pro-apoptotic proteins and at the cellular level by studying DNA fragmentation and annexin V staining by flow cytometry. The aqueous extract of Urtica dioica showed antioxidant effects with a correlation coefficient of r 2 =0.997. Dose-dependent and anti-proliferative effects of the extract were observed only on MCF-7 cells after 72 hrs with an IC 50 value of 2 mg/ml. This anti proliferative activity was associated with an increase of apoptosis as demonstrated by DNA fragmentation, the appearance of apoptotic cells in flow cytometry analysis and an increase of the amount of calpain 1, calpastatin, caspase 3, caspase 9, Bax and Bcl-2, all proteins involved in the apoptotic pathway. This is the first time such in vitro antiproliferative effect of aqueous extract of Urtica dioica leaf has been described for a breast cancer cell line. Our findings warrant further research on Urtica dioica as a potential chemotherapeutic agent for breast cancer.

SAT and 2-ME may be found in significant titers in less than 5% of clinically treated cases after two years. Serologic cure for both tests with lower titers were higher than with higher titers.
