Although northern blot analysis provides a direct evidence to determine precursor and mature form of miRNA, there is a possiblity that the sensitivity of notthern blotting may not be sufficient enough to detect lowly expressed miRNAs.
This theory is in clear juxtaposition to operant models of human behavior that identify learning history and reinforcement as determined precursors of behavior (Skinner 1974).
China also supports "Research on Determining Precursor Ionospheric Signatures of Earthquakes by Ground-based Ionospheric Sounding" and "Electromagnetic Satellite Payload for Earthquake Prediction" in the framework of the Asia Pacific Space Cooperation Organization (APSCO).
Top-down shotgun strategy takes advantage of high mass resolution of modern mass spectrometers, such that lipids of major classes could be recognized by accurately determined precursor masses with no recourse to MS/MS.
Second, the volatility of the cobalt precursor determines the precursor decomposition and nucleation process.
A full scan mass spectrum was achieved to determine the precursor ions.
Time of flight mass spectroscopy (TOF-MS) has been used to determine the precursor molecules created in the irradiation of benzene and shows the importance of ring-opening reactions in particle formation.
According to Hauser et al., the only real evolutionary mystery about language is how this capacity for recursion evolved — and this question, argue Hauser et al, is eminently addressable by normal biological methods (e.g., comparative studies to determine possible precursor mechanisms, etc).
The purpose of the present study was to determine whether precursor events are associated with a composite endpoint of major adverse cardiac events (MACE) (death, acute renal failure, stroke, infection) in a low- to medium-risk coronary artery bypass grafting, valve, and valve plus coronary artery bypass grafting population.
With this novel platform, we were able to determine the precursor pool-adjusted turnover rates of over 900 proteins in mouse liver.
