However, histology did not improve after WT-MSCs administration, maybe due to insufficient numerosity; similarly, protein content in BAL was not reduced by MSCs, but this could have followed direct extravasation after acid-induced physical disruption of the alveolar epithelial integrity.
This could be attributed to the fact that the lignocellulosic materials in sawdust are generally low in protein content and thus insufficient for the cultivation of mushrooms (Obodai et al. 2002).
In the anti-KC (Figure 3) and neutrophil depletion (Figure 4) experiments, cytokine concentrations in the lung homogenate were not normalized for total protein content due to insufficient sample volume and therefore expressed as picogram per millilitre.
However, protein content of Araucaria was insufficient for this plant to have served as the sole food source of a growing sauropod (Hummel et al., 2008).
Insufficient protein-folding capacity in the endoplasmic reticulum (ER) induces the unfolded protein response (UPR).
Protein spots identified as interesting in the non-FDR correlated one-way ANOVA and the PLS-DA modelling were not all identified with MALDI-TOF-MS, due to low protein content in the gel spot and a further insufficient access of biopsy material.
The reduction in protein content with 60%% w/v moisture could be due to insufficient water which did not allow good diffusion of solutes and gas, thereby slowing cell metabolism because of a lack of substrates or through too high concentration of inhibitive metabolites in or near the cell (Gervais and Molin, 2003).
However, in that latter study, failure may have been due to a lack of material, since Steen et al. performed the analyses with only 2.3 × 106 FIZ per sample (0.9 × 106 FIZ mg animal prot−1, and a protein content of 1.0 mg animal protein per anemone), which is insufficient for the sensitivity of 31P NMR.
Most likely the differences in weight gain can be attributed to intra- and inter-individual variability of human milk composition, particularly the early decline in protein content of human milk during lactation [ 11], resulting in insufficient protein supply in some infants predominantly receiving human milk if current standardized fortification is applied [ 7].
Twenty suitable studies were within our inclusion criteria and were discussed with RM: 10 were excluded due to the study not being aimed at establishing differences in GE of feeds related to protein content, or using only breast milk, comparing different hydrolysed feeds only or insufficient information on feeds used.
