Many routes to a micro RNA [PDF]
AbstractMicro RNAs (miRNAs) are ∼22 nt small RNAs that function as posttranscriptional negative regulators of gene expression. Thousands of these molecules have so far been identified across the metazoan and plant kingdoms. Although most miRNAs share the same biogenesis pathway, numerous noncanonical miRNAs and other small RNAs have also been ...

A micro RNA mediates shoot control of root branching [PDF]
Plants extract mineral nutrients from the soil, or from interactions with mutualistic soil microbes via their root systems. Adapting root architecture to nutrient availability enables efficient resource utilization, particularly in patchy and dynamic ...

Prediction of lung overdistension during mechanical ventilation using micro-RNA and gene expression [PDF]
Background Overstretching of lung parenchyma may lead to injury, especially during mechanical ventilation. To date, there are no specific biomarkers of lung stretch, but transcriptomic signatures have not been explored.

Blood serum microRNA profiles of pregnant women as biomarkers of pre-eclampsia evaluation
Introduction Pre-eclampsia is a pregnancy-related syndrome characterized by hypertension and proteinuria that makes its appearance after 20 weeks of gestation. It develops approximately in 2–10% of all pregnancies. Pre-eclampsia, as a severe complication

A Theory of Biodiversity and Gene Evolution [PDF]
The statement of theory: {Evolution of organisms and biodiversity depends mainly on gene evolution through the appearance of novel genes. Biodiversity results from the DNA modifications induced by visible and non-visible environmental effects, the ...
