Medical and Biotech [MESH] Definitions
RNA, usually prepared by transcription from cloned DNA, which complements a specific mRNA or DNA and is generally used for studies of virus genes, distribution of specific RNA in tissues and cells, integration of viral DNA into genomes, transcription, etc. Whereas DNA PROBES are preferred for use at a more macroscopic level for detection of the presence of DNA/RNA from specific species or subspecies, RNA probes are preferred for genetic studies. Conventional labels for the RNA probe include radioisotope labels 32P and 125I and the chemical label biotin. RNA probes may be further divided by category into plus-sense RNA probes, minus-sense RNA probes, and antisense RNA probes.
Ligase Chain Reaction
A DNA amplification technique based upon the ligation of OLIGONUCLEOTIDE PROBES. The probes are designed to exactly match two adjacent sequences of a specific target DNA. The chain reaction is repeated in three steps in the presence of excess probe: (1) heat denaturation of double-stranded DNA, (2) annealing of probes to target DNA, and (3) joining of the probes by thermostable DNA ligase. After the reaction is repeated for 20-30 cycles the production of ligated probe is measured.
Dna Probes, Hpv
DNA probes specific for the identification of human papilloma virus.
A technique for visualizing CHROMOSOME ABERRATIONS using fluorescently labeled DNA probes which are hybridized to chromosomal DNA. Multiple fluorochromes may be attached to the probes. Upon hybridization, this produces a multicolored, or painted, effect with a unique color at each site of hybridization. This technique may also be used to identify cross-species homology by labeling probes from one species for hybridization with chromosomes from another species.
Liver Cirrhosis, Alcoholic
FIBROSIS of the hepatic parenchyma due to chronic excess ALCOHOL DRINKING.
This study will examine the effectiveness of the FibroScan device in differentiating fibrosis in patients with hepatitis B and C. The FibroScan measures liver stiffness and will be correla...
The aim of this study is to evaluate liver fibrosis using FibroScan and biochemical markers in patients treated with methotrexate.
Apart from Fibrotest, non-invasive markers have been validated only for chronic hepatitis C. However as for chronic C hepatitis, non invasive tests (Fibrotest and transient elastometry) ar...
Non-alcoholic fatty liver disease (NAFLD) is now recognised as the hepatic complication of the metabolic syndrome of insulin resistance. In some patients, the disease can progress into ste...
This study will evaluate the effectiveness of Acoustic Radiation Force Impulse (ARFI)- Imaging compared to Transient Elastography (FibroScan) in differentiating liver fibrosis in patients...
FibroScan is one of the noninvasive techniques based on the transient elastography that can assess the progression of liver fibrosis in chronic hepatitis patients in daily clinical practice. Recently,...
Abstract Background. Methotrexate is an effective treatment for inflammatory bowel disease (IBD). However, long-term treatments have been associated with the development of liver fibrosis. FibroS...
Aim: To evaluate the association between liver stiffness measured by transient elastography (FibroScan) and the efficacy of long-term nucleoside analog (NA) treatment for patients with chronic hepa...
BACKGROUND : Although histopathological examination by "invasive" liver biopsy remains the gold standard for evaluating disease progression in chronic liver disease, noninvasive tools have appeared an...
BACKGROUND: Transient elastography (with the FibroScan((R)) apparatus) is a recently developed method for evaluating the severity of liver fibrosis by measuring liver elasticity. Liver elasticity may...
