Cancer Occurrence in Fars Province, Southern Iran

Abstract: Background: Cancer is a significant health problem in the developing countries, and one that is likely to increase in future. Due to unavailability of data concerning cancer during the last 15 years in our area and young age structure of our country, this active hospital-based study was undertaken to determine the occurrence of cancer in Fars Province, southern Iran. Methods: Data including face-to-face interview with patients and a survey of their medical and demographic records in relation to all invasive cancers were actively collected from 1990 to 2005 from four university hospitals. Among 2993 cases of registered malignant neoplasms presented by site and sex, the crude incidence (CRs), and age-specific incidence and age-standardized incidence rates (ASRs) per 100,000 were determined, using the world standard population. Results: Over a 5-year period, 1495 and 1620 cancer cases were registered in males and females, respectively, while breast cancer was at the top of 10 cancers in both sexes. Conclusion: With regard to the top 10 types of cancer, there was a remarkable difference between the results of our study and the estimated cancer incidence for Iran by Globocan 2000. Ethnic, racial and environmental factors may explain these differences but more studies in a longer time span are needed to clarify the causes.

Novel developments and trends of analytical methods for drug analysis in biological and environmental samples by molecularly imprinted polymers

Abstract: Because of the low concentration levels in plasma, blood, urine, and other metabolites, adequate analytical methods should be used for quantification of drugs at the trace levels. Molecularly imprinted polymers (MIPs) are tailor made and stable polymers with special molecular recognition abilities that because of their high selectivity can be used for the extraction of selected target analytes and structurally related analogues in many bioanalytical approaches. Nowadays, MIPs are rapidly progressing for the analysis of drugs in biological, environmental, and pharmaceutical samples. In this review, we discuss the novel developments and uses of MIPs as new sorbents and fibers in solid phase extraction (SPE) and solid phase microextraction (SPME), ultrasonic-assisted SPE, sensitive sensors, magnetic separations or conjugating with carbon materials for trace and ultra-trace determination of drugs. We believe that our review will be of assistance to drug analysis and analytical methods with highly selective separations/detections.

Functionality of nano titanium dioxide on textiles with future aspects: focus on wool

Abstract: The consumption of titanium dioxide in today's world is on the increase. As the most popular nano substance, TiO2 is used in various industries notably in the textile industry. More and more recently, through a synergistic combination of photocatalytic features of nanoparticles, fabrics with novel properties are produced. Self-cleaning and stability against UV rays as well as chemical media, to name but a few, are among new prominent properties, obtained on textiles. A common subject reported in most studies has been the diverse approaches to immobilize the nanoparticles on the surface of fabrics. Wool is among common textile materials that have undergone numerous processes to be modified. This review intends to bring to light different aspects of application of nano titanium dioxide in the textile industry especially on wool, and also presents a concise overview on the rigorous pieces of research conducted in this realm.
