In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure.
Answer:
FLACC stands for the Face, Legs, Activity, Cry, and Consalibility scale. Children should be between 2 months to 7 years of age. The form of evaluation is a scale from 1-10 to describe pain.
Explanation:
the function of DNA?
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information
Atherosclerosis refers to build up of plaques in blood vessels. This leads to obstruction of blood flow which results in mortality. The plaque development occurs at endothelial cells. This research by Dai, et al., 2004 aims to understand the functional and non functional physical features of endothelial cells in condition of specific blood flow pattern. They utilized 3D flow analysis to characterize flow patterns and used "athero-prone" and "athero-protective" waveforms. These were found to represent shear stress on carotid artery that could easily develop or resist formation of atherosclerotic lesion.
The analysis of results were done via cDNA microarrays for gene expression. The effect of waveforms was also checked through different parameters like expression and localization of junctional proteins, expression of adhesion molecules and expression of proinflammatory cytokines etc. The researchers conclude presence of phenotypic alteration depending upon shear stress in atherosclerosis sensitive and resistant human arterial geometries.
