nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
The risk of false positive results in noninvasive prenatal diagnosis focused on fetal gender and RhD status determination could be a problem in clinical routine. This is because these tests are based on detection of presence of DNA sequences with high population frequency and so there is the risk of sample contamination during sample collection and processing. In our study the different fragmen...
PURPOSE There is a quest for novel noninvasive diagnostic markers for the detection of breast cancer. The goal of this study is to identify circulating microRNA (miRNA) signatures using a cohort of Asian Chinese patients with breast cancer, and to compare miRNA profiles between tumor and serum samples. EXPERIMENTAL DESIGN miRNA from paired breast cancer tumors, normal tissue, and serum sample...
BACKGROUND Clinical and histopathologic assessment of pigmented skin lesions remains challenging even for experts. Differentiated and accurate noninvasive diagnostic modalities are highly desirable. OBJECTIVE We sought to provide clinicians with such a tool. METHODS A 2-gene classification method based on LINC00518 and preferentially expressed antigen in melanoma (PRAME) gene expression was...
As crucial small regulatory molecules, serum microRNAs (miRNAs) have been widely identified as potential noninvasive biomarkers. To survey and identify serum miRNAs associated with workers who had experienced injury to their nerve system from carbon disulfide (CS2), we profiled abnormally expressed miRNAs using the microarray technique and further performed qRT-PCR validation in case and contro...
BACKGROUND Multiplex digital PCR (dPCR) enables noninvasive and sensitive detection of circulating tumor DNA with performance unachievable by current molecular-detection approaches. Furthermore, picodroplet dPCR facilitates simultaneous screening for multiple mutations from the same sample. METHODS We investigated the utility of multiplex dPCR to screen for the 7 most common mutations in codo...
BACKGROUND The use of fetal DNA in maternal plasma for noninvasive prenatal diagnosis of trisomy 21 (T21) is an actively researched area. We propose a novel method of T21 detection that combines fetal-specific epigenetic and genetic markers. METHODS We used combined bisulfite restriction analysis to search for fetal DNA markers on chromosome 21 that were differentially methylated in the place...
We report four Indonesian cases meeting the clinical and radiological criteria for community-acquired pneumonia and other findings suggestive of leptospirosis. Quantitative PCR (qPCR) analyses of serum and urine samples and serology confirmed the diagnosis of leptospirosis in each. Results of qPCR analysis of throat swabs were concordant with those obtained with acute-phase serum samples, which...
