The development and function of neuronal circuits within the brain are orchestrated by sophisticated gene regulatory mechanisms. Recently, microRNAs have emerged as a novel class of small RNAs that fine-tune protein synthesis. microRNAs are abundantly expressed in the vertebrate nervous system, where they contribute to the specification of neuronal cell identity. Moreover, microRNAs also play a...

MicroRNAs form an essential class of post-transcriptional gene regulator of eukaryotic species, and play critical parts in development and disease and stress responses. MicroRNAs may originate from various genomic loci, have structural characteristics, and appear in canonical or modified forms, making them subtle to detect and analyze. We present miRvial, a robust computational method and compa...

cardiovascular disease has become the main factor of death and birth defects in the world. there are some therapeutic structures and drugs for curative and palliative therapy of the disease, but to the aim of accessing reliable therapy or to postpone onset of disease, especially for individuals with heritable coronary artery disease in their pedigree genetic engineering technologies are making ...

Accumulating papers have demonstrated that microRNAs play an important role in the progression of lung cancer, mainly as oncogenic and tumor suppressive. Therefore, microRNAs may influence the survival of lung cancer patients. In this meta-analysis, we evaluated the role of microRNAs in affecting the overall survival in nonsmall cell lung cancer (NSCLC) patients, which may provide valuable info...

microRNAs are a type of small non-coding RNAs which play important roles in post-transcriptional gene regulation, and the characterization of microRNA expression profiling in peripheral blood mononuclear cells (PBMCs) from patients with Klinefelter syndrome requires further investigation. In this study, PBMCs were obtained from patients with Klinefelter syndrome and normal controls. After prepa...

MicroRNAs are small, noncoding RNA molecules that regulate target gene expression in the posttranscriptional level. Unlike siRNA, microRNAs are "fine-tuners" rather than "switches" in the regulation of gene expression; thus they play key roles in maintaining tissue homeostasis. The aberrant microRNA expression is implicated in the disease process. To date, numerous studies have demonstrated the...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a kind of primary cardiomyopathy characterized by the fibro-fatty replacement of right ventricular myocardium. Currently, myocardial microRNAs have been reported to play critical role in the pathophysiology of cardiovascular pathophysiology. So far, the profiling of microRNAs in ARVC has not been described. In this study, we applied S-Po...

BACKGROUND Bronchopulmonary dysplasia (BPD) is a chronic lung disease of preterm neonates; the underlying pathogenesis is not fully understood. MicroRNAs (length 21-25 nucleotides) are ribonucleic acid (RNA) molecules that have important functions in development, cellular differentiation, apoptosis, proliferation, and migration; very little is known regarding their role in developmental lung di...

Study Design: Descriptive cross-sectional study. Methodology: Aplastic were assessed for level and considered if was ≥2 Results: Majority 20(66.7%) aged ≤30 years only 10(33.3%) above 30 years. There 22(73.3%) male 8(2...

the importance of nanotechnology in medical technologies, especially biomedical diagnostics, is indubitable. by taking advantages of nanomaterials, many medical diagnostics methods have been developed so far, including electrochemical nanobiosensors. they have been used for quantification of different clinical biomarkers for detecting, screening, or follow up a disease. micrornas (mirnas) are o...
