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.

Two series of 2-(5-nitro-2-furyl)- and 2-(1-methyl-5-nitro-1H-imidazol-2-yl)-5-propyl, allyl and propargyl)thio-1,3,4-thiadiazoles (6a-f) and 2-(5-nitro-2-furyl)- and 2-(1-methyl-5-nitro-1 H-imidazol-2-yl)-5-(nitrobenzyl)thio-1,3,4-thiadiazole derivatives (8a-f) have been synthesized and evaluated against Mycobacterium tuberculosis, as part of the TAACF TB screening program under direction of the US National Institute of Health, the NIAID division. Primary screening was conducted at a single concentration, 6.25 $\mu\textrm{g}$mL$^{-1}$ , against M. tuberculosis H$_{37}$ Rv in BACTEC 12B medium, using the Microplate Alamar Blue Assay (MABA). The minimum inhibitory concentration (MIC) was determined for the compounds that demonstrated $\geq$90% growth inhibition in the primary screening. A varying degree of antituberculosis activity (from 0-97% of growth inhibition) was observed with the alkylthio series (6a-f), and the nitroimidazole derivative with a propylthio group (6b) and the nitrofuran derivative with a propargylthio group (6e), were the most active compounds (MIC=3.13 and 1.56 /$\mu\textrm{g}$mL$^{-1}$ , respectively). Among the nitrobenzylthio derivatives (8a-f), all the ortho, meta and para nitrobenzyl isomers in the nitrofuran series exhibited good antituberculosis activity (MIC=3.13 $\mu\textrm{g}$mL$^{-1}$ ), while the corresponding nitroimidazole analogues were completely inactive (Inhibition=0%).

Gastric cancer (GC) is a multifactorial disease with different factors having roles in its genesis. Helicobacter pylori and Epstein-Barr virus (EBV) are known infectious agents that could contribute. In addition, there is evidence of a relationship with cytomegalovirus (CMV). Since data on CMV prevalence in gastric cancer are limited, we here evaluated the frequency of EBV and CMV in Iranian patients. Ninety paraffin blocks of GC tissues from patients in Kerman were evaluated for the presence of EBV and CMV genomes by real-time polymerase chain reaction. EBV was detected in 10 cases (11.1%) and CMV in seven. One out of 17 female patients (5.88%) and nine out of 73 male patients (12.3%) were positive for EBV, while one out of 17 female patients (5.88%) and six out of 73 male patients (8.22%) were positive for CMV. The mean age for EBV-positive patients was $60.5{\pm}14.9years$ and the mean age for CMV-positive patients was $67.9{\pm}12.3years$. This study shows that the frequency of EBV-associated GC is high in Kerman. It also indicates that further studies of associations between GC and CMV are warranted, covering larger samples and populations from different areas of the world.

In this study, we carried out extensive in vitro studies on various concentrations of tioxolone along with benzoxonium chloride and their niosomal forms against Leishmania tropica. Niosomes were prepared by the hydration method and were evaluated for morphology, size, release study, and encapsulation efficiency. This study measured leishmanicidal activity against promastigote and amastigote, apoptosis and gene expression levels of free solution and niosomal-encapsulated tioxolone along with benzoxonium chloride. Span/Tween 60 niosome had good physical stability and high encapsulation efficiency (more than 97%). The release profile of the entrapped compound showed that a gradual release rate. The combination of niosomal forms on promastigote and amastigote were more effective than glucantime. Also, the niosomal form of this compound was significantly less toxic than glucantime ($P{\leq}0.05$). The flowcytometric analysis on niosomal form of drugs showed that higher number of early apoptotic event as the principal mode of action (89.13% in $200{\mu}g/ml$). Also, the niosomal compound increased the expression level of IL-12 and metacaspase genes and decreased the expression level of the IL-10 gene, which further confirming the immunomodulatory role as the mechanism of action. We observed the synergistic effects of these 2 drugs that induced the apoptotic pathways and also up regulation of an immunomodulatory role against as the main mode of action. Also, niosomal form of this combination was safe and demonstrated strong anti-leishmaniasis effects highlights further therapeutic approaches against anthroponotic cutaneous leishmaniasis in future planning.

There is no effective treatment modality available against different forms of leishmaniasis. Therefore, the aim of this study was to improve the penetration and efficacy of selenium and glucantime coupled with niosomes and compared them with their simple forms alone on in vitro susceptibility assays. In this study, the niosomal formulations of selenium and in combination with glucantime were prepared. The size and morphology of the niosomal formulations were characterized and the effectivity of the new formulation was also evaluated using in vitro MTT assay, intra-macrophage model, and gene expression profile. From the results obtained, no cytotoxicity effect was observed for niosomal and simple forms of drugs, as alone or in combination. Niosomal formulations of the drugs significantly showed more inhibitory effects ($P{\leq}0.001$) than the simple drugs when the selectivity index was considered. The gene expression levels of Interleukin (IL-10) significantly decreased, while the level of IL-12 and metacaspase significantly increased ($P{\leq}0.001$). The results of the present study showed that selenium plus glucantime niosome possess a potent anti-leishmanial effect and enhanced their lethal activity as evidenced by the in vitro experiments.

Background: Gastrointestinal cancers are common malignancies associated with high mortality rates. Healthcare systems are always faced with high costs of treatment of gastrointestinal cancers including stomach cancer. Identification and prioritization of these costs can help determine economic burden and then improve of health planning by policy-makers. This study was performed in 2015 in Kerman City aimed at estimating the direct hospital costs for patients with gastric cancer. Materials and Methods: In this cross-sectional study, the medical records of 160 patients with stomach cancer admitted from 2011 to 2014 to Shafa Hospital were examined, the current stage of the disease and the patients' health status were identified, and the direct costs related to the type of treatment in the public and private sectors were calculated. SPSS-19 was used for statistical analysis of the data. Results: Of the patients studied, 103 (65%) were men and 57 (35%) were women. The mean age of patients was 65 years. Distribution into four stages of the disease was 5%, 20%, 30%, and 45%, respectively. Direct costs in four stages of the disease were calculated as 2191.07, 2642.93, 2877, and 2674.07 USD (63,045,879, 76,047,934, 82,783,019, and 76,943,800 IRR), respectively. The highest percentage of costs was related to surgery in Stage I and to medication in Stages II, III, and IV. According to the results of direct costs of treatment for stomach cancer in Kerman, the mean total cost of treating a patient in the public sector was estimated at 74,705,158 IRR, of which averages of 60,141,384 IRR and 14,563,774 IRR were the shares of insurance and patients, respectively. Conclusions: The high prevalence and diagnosis of disease in old age and at advanced stages of disease impose great costs on the patients and the health system. Early diagnosis through screening and selecting an appropriate treatment method might largely ameliorate the economic burden of the disease.

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.
