Lung cancer has long been a major health problem in China. This study aimed to examine the temporal trend and spatial pattern of lung cancer mortality in Shandong Province from 1970 to 2013. Lung cancer mortality data were obtained from Shandong Death Registration System and three nationwide retrospective cause-of-death surveys. A Purely Spatial Scan Statistics method with Discrete Poisson mode...
The incidence of adult brain cancer was previously shown to be higher in countries where the parasite Toxoplasma gondii is common, suggesting that this brain protozoan could potentially increase the risk of tumor formation. Using countries as replicates has, however, several potential confounding factors, particularly because detection rates vary with country wealth. Using an independent datase...
The main objective of the study was to analyze the effect of age, period and birth cohort on esophageal cancer mortality in Brazil and its geographic regions, per sex. An ecological study is presented herein, which evaluated the deaths by esophageal cancer and the distribution, per geographic region. Poisson Regression was utilized to calculate the effects of age, period and birth cohort, and p...
conclusions: using these factors, nephrologists may predict the occurrence of graft loss or death. if the probability of graft loss was higher, physicians can decrease the immunosuppressive medications dosage to decrease the incidence of graft loss. patients and methods: fine-gray model was used for 266 cases with post-transplant malignancy in iran. these patients were followed-up from the diag...
The concept of alternative stable states has long been a dominant framework for studying the influence of historical contingency in community assembly. This concept focuses on stable states, yet many real communities are kept in a transient state by disturbance, and the utility of predictions for stable states in explaining transient states remains unclear. Using a simple model of plant communi...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
This work extends prior research that finds drug development is driven by demand factors such as mortality rates of the diseases new drugs are aimed at. Here we find that the number of drugs in the development pipeline is strongly positively related to the price of existing drugs treating those diseases. [JEL: O-34, I-11]
Abstract Background: There is no reliable prediction model on the rate of mortality due to road traffic accidents in Iran. The present study aimed to predict deaths from road traffic crashes in Iran. Materials and methods: All death records from traffic accidents in Iran between March 2004 and March 2011 were analyzed. The Box-Jenkins time series model was used for obtaining trends. Death f...
پلی اتیلن ایمین (pei) یک پلیمر پلی آمینی است که در مطالعات سلولی و بافتی به عنوان حامل غیر ویروسی کاربردهای موفقیت آمیزی داشته است. متاسفانه این ترکیب معایبی نیز دارد، از جمله اینکه منجر به سمیت سلولی می شود. اما مکانیسم های ایجاد سمیت آن هنوز به درستی شناخته نشده است. استفاده از تکنیک ترانسکریپتوم در شناسایی ژن های درگیر در فرایند آپوپتوزکمک شایانی به مشخص شدن مکانیسم سمیت این ترکیب می کند. ...
