introduction: development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. blood brain barrier (bbb) opening is an important part of edema named as vasogenic brain edema. in this study, quantitative alterations of bbb permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. methods: two groups of male rats (ischemic and sh...

lineaments are the most important phenomena of geological exploration of hydrocarbon reservoirs . concepts in order to map the contours of land need so much time and money. one of the most famous methods in lineaments extraction is satellite image processing. in this paper, an overview of lineament extraction methods and a new method based on canny edge detection algorithm is raised. the result...

Mapping expression quantitative trait loci (eQTL) has identified genetic variants associated with transcription rates and has provided insight into genotype-phenotype associations obtained from genome-wide association studies (GWAS). Traditional eQTL mapping methods present significant challenges for the multiple-testing burden, resulting in a limited ability to detect eQTL that reside distal t...

Accurate and rapid diagnosis of human cytomegalovirus (HCMV) disease in immunocompromised patients has remained as a challenge. Quantitative competitive PCR (QC-PCR) methods for detection of HCMV in these individuals have improved the positive and negative predictive values of PCR for diagnosis of HCMV disease. In this study we used QC-PCR assay, using a co-amplified DNA standard, to quantitate...

background and objectives: hbv dna monitoring is important in management of chronic viral hepatitis b infection. hbv dna measurements are carried out over period of months to years. so the analytical system must be stable and reproducible. the aim of this study was to determine the performance characteristics and to plan a statistical quality control system of a laboratory-developed real-time q...

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...

Listeria monocytogenes is a species of foodborne pathogen often related to foods, such as poultry, ready-to-eat products, fruits, and vegetables. The culture method is a standard procedure for the detection of bacteria in food products. The real-time quantitative PCR (qPCR) technique can be used for the quantification of foodborne pathogens. The current research was aimed to assess...
