the eukaryotic complexity involves the expression and regulation of genes via rna-dna, rna-rna, dna-protein and rna-protein interactions. recently, the role of rna molecules in the regulation of genes in higher organisms has become more evident, especially with the discovery that about 97% of the transcriptional output in higher organisms are represented as noncoding rnas: rrna, snornas, trna, ...

despite the major advances in conventional forms of treatment (i.e. surgical techniques, radiotherapy and chemotherapy) and improved survival rates, cancer is still the second leading cause of death in developing countries. one major limitation of cytotoxic drugs and radiation in the treatment of cancer patients is their inability to discriminate between malignant and normal tissues. this in tu...

background: the incidence of colorectal cancer is rising in several developing countries. in the absence of integrated endoscopy and pathology databases, adenoma detection rate (adr), as a validated quality indicator of screening colonoscopy, is generally difficult to obtain in practice. we aimed to measure the correlation of polyp-related indicators with adr in order to identify the most accur...

Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...
