Slightly different from classifying disease status (discrete label), another family of problems uses tensor neuroimages to predict cognitive outcome (continuous label).
Protein synthesis can be conveniently measured by use of a continuous label administration, rise-to-plateau approach, based on the incorporation of deuterium (2H) from heavy water (2H2O) into nonessential amino acids (NEAA) in newly synthesized proteins[6].
In contrast to the conventional studies of bacteria in a stationary fluid, this work demonstrates continuous label-free trapping and alignment of biological entities in flowing fluids in a simple microchannel with low cost microfluidic chip fabrication, facile sample preparation and remote isothermal control of trapping by small uniform magnetic fields.
The use of this continuous labeling technique allows precise determination of G1 delays [67].
An additional experiment was performed with 6 hours continuous labeling to distinguish all high/low sulfur containing proteins (data not shown).
We therefore injected the BrdU i.p. to pulse-label islet cells, and as expected found a substantially lower percentage of labeled endocrine cells (0.42%, Figure 3A) compared to the 7d-drinking-water continuous labeling technique (8.7%).
For 24 hours continuous labeling, after the described incubation, culture medium supplemented with 1 mM ATP, 10 µM biotin, 30 mM di-sodium phosphocreatine and 30 U/mL creatine phosphokinase was added to the reaction.
Yet, the frequency of BrdU+ DN T cells in peripheral blood steadily increased and exceeded that of BrdU+ SP T cells by day 7 of continuous labeling (Fig. 6E).
For the steady-state analysis, anti-CD8, anti-β1 integrin or anti-CIMPR antibody was added to the culture medium for 45 min at 37°C before fixation to enhance the internalization signal by allowing continuous labeling and internalization.
Cells were re-stimulated to enter the cell cycle (into G1) by addition of isoleucine-containing MEM or medium containing EGF. Replicating DNA was labeled by either pulsing for 30 minutes with bromodeoxyuridine (BrdU; 15 µM) at the indicated time points, or by continuous labeling with BrdU (20 µM) throughout the experiment.
