Colorectal cancer is one of the most common cancers. The aim of this study is determination its trends in Kerman province and individual cities separately until year 2016. This analytical and modeling study was based of cancer registry data of Kerman University of Medical Sciences, collected during 2001-2010. Among 20,351 cancer case, 792 were colorectal cancer cases in age group 18-93 years with a mean of 59.4 and standard deviation of 15.1. By applying time series and data trends, incidences were predicted until 2016 for the province and each city, with adjustment for population size. In colorectal cases, 413 (52%) were male, and 379 (48%) were female. The annual increasing rate in Kerman province overall was and can be expected to be 6%, and in the cities of the province Rafsanjan, Bardsir, Bam, Kerman, Baft, Sirjan, Jiroft, Kahnuj and Manujan had an increasing range from 5 to 14% by the year 2016. But in Ravar, Zarand and Shahrbabak reduction in rates of at least 2% could be predicted. The time series showed that the trend of colorectal cancer in female will increase 15% and in male 7% by year 2016. Given the trend of this cancer is increasing so that resources will be consumed in the treatment of the patients, efforts shoudlbe focused on prevention and early diagnosis of the disease. Screening could have an important role leading to improved survival.

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.

Prostatic cancer is the second cause of cancer-related death among men worldwide. The human papilloma viruses (HPVs) are a family of sexually transmitted viruses which have may have roles in the ethiology of inflammation in prostate leading to benign prostatic hyperplasia (BPH) and prostate cancer (PCa). In this study, we evaluated the frequency of different HPV types in prostatic cancer and benign prostatic hyperplasia (BPH) in Kerman province, southeast of Iran, using real-time PCR techniques. The aim of the present research was to clarify any association with prostatic carcinogenesis. Real Time PCR showed that HPV DNA was found in 20% of 200 PCa samples, 80 percent of these with high-risk HPV types, 40% with type-16,18, 30 % type-31,33 and 10% type 54. High risk HPV DNA was detected in only 2% of BPH samples. Values for low risk types were much higher. Our study provided a support for the role of high risk HPV infection in prostatic disease in Iranian patients, and association between presence of HPV DNA and prostate carcinoma. In particular, HPV 16 and18 might have an important role in prostate cancer.

Rates based on age-adjusted incidence of colorectal cancers over a 10-year period in Kerman, the biggest province of Iran, were estimated from 2003 to 2013. Data were obtained from the population-based cancer registry unit of Kerman University of Medical Sciences (CR-KMU). Information included age, sex, city, ICD-O and year of registry. Our trend analyses cover 3.91% of the Iranian population. The data set comprised cases diagnosed from 2003 to 2013.The population of over 20 years was interpolated using 2003 and 2010 censuses. Then, truncated age-adjusted incidence rates were calculated. Increase was noted from 2003-2009 to 2010-2013 for 731 cancer cases considered in the analysis. The increases was most prominent in 2009. Totally, the frequency of the cancer was greater in males. Moreover, calculating truncated age-adjusted incidence rate indicated that the most prevalent age of colorectal incidence was in the 50-59 year age group except in 2007-2008 and 2012- 2013, when greatest incidences occurred in people aged 60-69 years. Our data revealed that the incidence rates of colorectal cancer have increased over the past decade in our region of Iran.

Background: Mammography screening is a method for reducing breast cancer mortality in women over 40 years old. A participation rate of at least 70% is a prerequisite for screening programs. This study aimed at determining the participation rate of women in breast cancer screening in Iran. Materials and Methods: The study population in this prospective research consisted of 35 to 69 years old women in the villages and towns Kerman District, in 2013. The data were collected by a well-validated risk assessment questionnaire. The questionnaires were completed with the help of health workers and technicians in the health centers, who were trained on breast cancer screening program. Results: As a whole, 19,651 women were invited to complete the questionnaire, of whom 15,794 women (80.37%) completed it. In the urban region, of 3150 eligible women 2728 women (86.60%) participated in the study. The acceptance rates for mammography in rural and urban regions were 34.95% and 8.75%, respectively. Conclusions: Finally, 3.8% and 16.34% of 35 to 69 years old women in the urban regions were mammographed, respectively. Conclusion: The low participation of eligible women in breast cancer screening program alerts us against including the program in the health insurance package.

This research presents an in-depth analysis of location planning of the solar-hydrogen power plants for electricity production in different cities situated in Kerman province of Iran. Ten cities were analyzed in order to select the most suitable location for the construction of a solar-hydrogen power plant utilizing photovoltaic panels. Data envelopment analysis (DEA) methodology was applied to prioritize cities for installing the solar-hydrogen power plant so that one candidate location was selected for each city. Different criteria including population, distance to main road, flood risk, wind speed, sunshine hours, air temperature, humidity, horizontal solar irradiation, dust, and land costare used for the analysis. From the analysis, it is found that among the candidates' cities, the site of Lalezar is ranked as the first priority for the solar-hydrogen system development. A measure of validity is obtained when results of the DEA method are compared with the results of the technique for ordering preference by similarity to ideal solution (TOPSIS). Applying TOPSIS model, it was found that city of Lalezar ranked first, and Rafsanjan gained last priority for installing the solar-hydrogen power plants. Cities of Baft, Sirjan, Kerman, Shahrbabak, Kahnouj, Shahdad, Bam, and Jiroft ranked second to ninth, respectively. The validity of the DEA model is compared with the results of TOPSIS and it is demonstrated that the two methods produced similar results. The solar-hydrogen power plant is considered for installation in the city of Lalezar. It is demonstrated that installation of the proposed solar-hydrogen system in Lalezar can lead to yearly yield of 129 ton-H2 which covers 4.3% of total annual energy demands of the city.

One of the critical limitations to use of bacteriocins produced by lactic acid bacteria as a substitute for chemical antibiotics is the narrow spectrum of their antibacterial activity. The aim of present study was isolation and molecular identification of bacteriocin-producing enterococci with broad antibacterial spectrum. Bacteriocin-producing bacteria were isolated from native dairies in Kerman. Bacteriocins were purified by ammonium sulfate method and the effects of them were investigated on different strains of bacteria. Also, the effects of pH and heat on produced bacteriocins were investigated. High level bacteriocin-producing isolates were identified based on molecular tests. A total of 15 strains of bacteriocin-producing Enterococcus were isolated initially. Enterococcus faecium C-2 and Y-1 strains produced bacteriocins with the highest antibacterial effect. The bacteriocins were stable in pH ranges from 2 to 12 and their antibacterial activity was maintained after autoclave treatment. The maximum bactericidal effect was observed against Listeria monocytogenes and Pseudomonas aeruginosa. In conclusion, use of these bacteriocins as a substitute for chemical antibiotics is recommended.

Due to the lack of nationwide population-based cancer registration, the total cancer prevalence in Iran is unknown. Our previous work in which we used a basic network scale-up (NSU) method, failed to provide plausible estimates of total cancer prevalence in Kerman. The aim of the present study was to estimate total and partial prevalence of cancer in southeastern Iran using an adapted version of the generalized network scale-up method. A survey was conducted in 2014 using multi-stage cluster sampling. A total of 1995 face-to-face gender-matched interviews were performed based on an adapted version of the NSU questionnaire. Interviewees were asked about their family cancer history. Total and partial prevalence were estimated using a generalized NSU estimator. The Monte Carlo method was adopted for the estimation of upper/lower bounds of the uncertainty range of point estimates. One-yr, 2-3 yr, and 4-5 yr prevalence (per 100,000 people) was respectively estimated at 78 (95%CI, 66, 90), 128 (95%CI, 118, 147), and 59 (95%CI, 49, 70) for women, and 48 (95%CI, 38, 58), 78 (95%CI, 66, 91), and 42 (95%CI, 32, 52) for men. The 5-yr prevalence of all cancers was estimated at 0.18 percent for men, and 0.27 percent for women. This study showed that the generalized familial network scale-up method is capable of estimating cancer prevalence, with acceptable precision.

The human papilloma virus (HPV) causes skin and mucous membrane infections. It crosses from one person to another by skin-to-skin contact, such as sexual contact. There are more than 100 types of HPV that can influence different parts of the body. Some types of HPV can cause cancer (such as cervical or anal cancer) and others can cause warts (such as genital or plantar warts). HPV infection is one of the most common sexually transmitted infections (STIs) in Iran and around the world. Considerable molecular evidence suggests a role for human papilloma virus (HPV) in the pathogenesis of carcinoma. Epidemiological studies on human papilloma viruses (HPVs) infections in general population are critical for the performing of health policy guidelines for developing the strategies to hinder the primary and secondary different cancer. In different parts of Iran, there is a lack of population-based studies to determine the prevalence of HPV in the general population. The aim of this population-based study was therefore to report the prevalence ratse of HPV types among Iranian patients. To study the risk of human papilloma virus (HPV) infection, we managed a retrospective study in Kerman province, southeast of Iran. For this purpose, 410 patients tested for the presence of HPV DNA using PCR and INNo-Lipa assays. HPV DNA was detected in 108 out of 410 patients (26.34%), while it was not detected in any of the control group samples. Patients included 23 (21.1%) males and 86 (78.8%) females. HPV type 6 was the most common (49%) followed by HPV type 16 (10.1%), and also HPV type11 (9.2%). The prevalence of HPV in Iran is comparable to those reported in other regions of the world. In a similar manner, it seems that HPV types 6, 16 and11 are the most common types in Kerman. Additional studies on larger group of patients, particularly in those with pre-invasive forms of disease, are needed to explain the roles of different HPV types in this location of Iran.

Background: Leukemia and lymphoma demonstrate significantly incidence rates throughout the world and particularly in Iran they cause serious mortality and diagnosis and treatment expenditures for both families and the health system. Combined they account for about 11 percent of cancers in Mazandaran province, ranking number 2 in prevalent cancers. The purpose of this study was to provide a first general and specific description of leukemia and lymphoma in Mazandaran province. Materials and Methods: In this descriptive retrospective study, entire patient's data were reviewed which had confirmed diagnosis of leukemia and lymphoma with valid laboratory or pathology reports in the period 2001-2008. The data were collected by Babol health research site related to Tehran University of Medical Science. Incidence rates based on age groups, gender, city of residence and type of malignancy were calculated and analyzed. Results: In Mazandaran province, 1,146 cases of leukemia and lymphoma were encountered, 5.9 in 100,000 persons on average annually. The highest incidence rates were obtained at age of 70 or above (26.4) and the lowest at age of 0-9 (2.3).The incidence rates in males and females were 7.1 and 4.8 respectively with a ratio of 1.5. The highest incidence rate was in Babol (7.3) and the lowest was calculated in Neka and Tonekabon equally (1.5). According to the type of malignancy, non Hodgkin lymphoma, with 2.5/100,000 have the most incidence rate and myeloid leukemia with 1.8 had the lowest. Conclusions: The obtained findings indicate clear differences in incidence rates based on age, gender, residence, and type of malignancy. Therefore it's suggested that in addition to promote data collecting programs, research projects should be programmed to define leukemia and lymphoma risk factors in this province.
