PURPOSE The high risk of recurrence after transurethral resection of bladder tumor of nonmuscle invasive disease requires lifelong treatment and surveillance. Changes in DNA methylation are chemically stable, occur early during tumorigenesis, and can be quantified in bladder tumors and in cells shed into the urine. Some urine markers have been used to help detect bladder tumors; however, their ...

Synergy of specific microRNAs (miRNAs) with cardiovascular risk factors to estimate atherosclerosis presence in ischemic stroke patients has not been investigated. The present study aimed to identify atherosclerosis-related circulating miRNAs and to evaluate interaction with other cardiovascular markers to improve the estimation of atherosclerosis presence. We performed a miRNA profiling study ...

With random amplified polymorphic DNA (RAPD) markers, we have tagged a genomic region in Populus sp. involved in qualitative resistance to Melampsora larici-populina. Our approach was based on three steps: use of RAPD markers that can be quickly and efficiently researched: application of "bulked segregant analysis" technique on individuals of one interspecific family P. trichocarpa x P. deltoid...

Atrial fibrillation is a heterogeneous disorder that is usually characterized by paroxysmal onset, particularly in patients without structural heart disease. Defining biological markers of atrial remodelling would help identify patients at high risk who would benefit most from prophylactic treatment and careful monitoring. Biomarkers of atrial fibrillation progression would be helpful for follo...

Tree breeding is basically aimed at producing quality products like seeds and clones and the most valuable contribution of molecular markers in breeding programs would be to reduce the time of selection or to reduce the number of breeding cycles. This can be achieved either by the early identification of superior progeny or by the identification of parents that will yield superior progeny. The ...

Digestibility markers are commonly used in animal nutrition studies, especially where the total collection of faecal material is not practical. Whilst it is customary to employ this methodology in production animal studies, digestibility trials in dogs and cats traditionally rely on the total collection of faeces. Consequently, there are relatively few reports of the use of inert markers in dog...

The overall mortality rate for ovarian cancer is 75%, but when diagnosed at stage I, 90% of patients can be cured. Strategies for early detection require high sensitivity (>75%) and extremely high specificity (99.6%) to attain a positive predictive value of at least 10%. When functioning alone, conventional markers fall short of this required sensitivity or specificity. Greater specificity can ...

Young children and the developing fetus may be more susceptible to effects of environmental toxicants than adults due to differential exposure patterns and developmental immaturities. Biologic markers offer the potential of quantitative dosimeters of biologic dose and/or indices of biologic effect associated with fetal/childhood exposures. They can facilitate evaluation of interindividual varia...
