Microarrays technologies are a relatively new development that allow biologists to monitor the activity of thousands of genes (normally around 8,000) in parallel across multiple stages of a biological process. While this new perspective on biological functioning is recognised as having the potential to have a significant impact on the diagnosis, treatment, and prevention of diseases, it is only...

Introduction: In Iran, invasive nontyphoidal Salmonella (iNTS) disease causes severe bacteremic illness among children <5 years old. The global yearly incidence of iNTS disease in children was reported to be in the 3.4 (range&nbsp; 2.1-6.5) million cases,&nbsp; (overall incidence 49 cases (range 30-94) per 100,000 population), the iNTS case-fatality ratio (CFR) of 20% yielded 681,316&nbsp; deat...

background: aflatoxin b1 (afb1) is a toxic metaboliteproduced by aspergillus species that contaminates a wide range ofagricultural products. objectives: this study was designed todevelop a rapid and highly sensitive immunoassay method inmicroarray format for quantitative detection of afb1 to evaluatethe potential of microarray platform for high-throughput screening,which can be beneficial in fo...

a long-lasting problem in the analysis of tissue samples is the time-consuming and repetitive process of histologic preparation and pathologic review of tissue sections. these two critical factors, innate nonuniformity in preparation and subjectivity of analysis, therefore limit the scientific and statistical thoroughness of tissue based studies. employing tissue microarray (tma) technique prov...

b a c k g r o u n d  & aim: it is very helpful to classify and predict the clinical  category  of a sample based  on  its  gene  expression  profile.  this  study  was  conducted  to predict  tissues  of colorectal adenoma,  adenocarcinoma,  and  paired  normal  in  colon  based  on  microarray  data  using  nearest shrunken centroid method. methods   &  materials:    in  this  study,   the  co...

The construction of gene regulatory models from microarray time-series data has received much attention. Here we propose a method that extends standard correlation networks to incorporate explicit timeslices. The method is applied to a time-series dataset of a study on gene expression in the developmental phase of zebrafish. Results show that the method is able to distinguish real relations bet...

DNA microarray technology provides a broad snapshot of the state of the cell by measuring the expression levels of thousands of genes simultaneously. Visualization techniques can enable the exploration and detection of patterns and relationships in a complex dataset by presenting the data in a graphical format in which the key characteristics become more apparent. The purpose of this study is t...
