introduction: this paper addresses a method for automatic detection of blood vessels in color fundus images which utilizes two main tools: image partitioning and local radon transform. material and methods: the input images are firstly divided into overlapping windows and then the radon transform is applied to each. the maximum of the radon transform in each window corresponds to the probable a...

cryptococcosis has become the fourth leading life-threatening opportunistic infection in patients with aids, but also occurs in non-aids patients. in view of the increasing numbers of infection during last decade in iran, use of rapid, sensitive and specific test for diagnosis of cryptococcal disease has become important than ever. we aimed to produce the reagents for latex cryptococcal antigen...

cancer, with a high rate of mortalities worldwide, pose a major threat to human health. although family history accounts for at least 5-10% of all cancers, it is conferred to be as a significant risk of developing cancer. recently, application of high speed and low cost high-throughput nucleotide sequencing technologies has provided an opportunity to assess cancer risk in at risk healthy indivi...

Cholinesterase (ChE) staining was used to reveal the timing and pattern of development of afferents to the prestriate visual cortex (areas 18, 19, 20, and 21 of Brodmann) in a series of developing human and monkey fetal brains. This investigation was possible because the nucleus pulvinaris of the thalamus, the main source of subcortical projections to the prestriate cortex, displays positive re...

breast cancer is the most important and prevalent cancer in women that can be managed if detected in the early stages. recently, there has been much focus on the use of epigenetic changes such as dna methylation in early detection of cancer. as recent research has put forth dok7 cpg island methylation as an epimarker, in the present study, using a quantification method, a cohort of iranian spor...
