It's a consequence of evolution that animals have used the same biological tricks to get what they need from the environment.
Each fraction was tested using the same biological activity model, and the dichloromethane fraction had the highest activity.
Mauro Maccarrone, of the Campus Bio-Medico University of Rome, Italy, and colleagues have revealed the highly-prized fungi produce anandamide, a compound that triggers the release of mood-enhancing chemicals in the human brain, and does so using the same biological mechanism as tetrahydrocannabinol (THC), the chemical responsible for producing the mind-bending effects of marijuana.
This conclusion is supported by cDNA microarray results from a large-scale study using the same biological material [ 23].
Extavia® (Novartis), launched in 2009, uses the same biological ingredient (IFN beta-1b) and administration route as Betaseron.
In addition, they are used in studies where treatment can have an effect on multiple events using the same biological pathway.
Moreover, comparison with the read counts from fragmented poly(A) + mRNA libraries prepared using the same biological samples reveals the relative contributions of changes in mRNA abundance and translational efficiency to regulation of protein production.
Using the same biological sample, the reference (untreated sample) is labeled twice, once with Alexa 546 and once with Alexa 647, and the variability between the two sets of measurements is calculated to estimate the experimental noise.
In this study, the former will refer to the degree of data variations among technical replicates of a platform, and the latter will refer to data agreement across different microarray platforms when using the same biological samples.
In order to better understand gene regulation in stems, data from transcriptomics were compared to those of a previous proteomic study performed using the same biological material, i.e. mature Arabidopsis stems [ 8].
