This assay was repeated using a PHB suspension previously subjected to sonication for 20 min at 4° C using a Labsonic sonicator (Braum Biotech International, Melsungen, Germany) in order to improve bioavailability of PHB. Yet, no significant differences were observed with these experiments (data ...
The potential of the PHB scaffolds containing OGP or OGP(10–14) peptides for inducing the calcium precipitation over scaffolds was indirectly evaluated by calcium quantification into culture supernatant using Cálcio Kit (Labtest Diagnóstica, Brazil). This methodology was previously confirmed in RBMSC...
Growth kinetics of the culture was studied in 2.0 L lab scale bioreactor. The profiles of PHB accumulation were analyzed in batch cultivation by growing on the cardboard industry waste water under optimized growth conditions obtained at flask level (Figure 4). The growth pattern for the microorgan...

Data are presented as means±SD from distinct samples. One-way ANOVA was used to analyse differences among groups, and differences between two groups were evaluated using the least significant difference test (two-tailed). Values ofp < 0.05 were considered statistically significant. Experiments ...
The response was averaged in the interval of peak vasorelaxation, from 5 to 10 minutes after application of the test compound, and reported relative to the pre-contraction level. Multiple concentra- tions of Na-3-OHB and NaCl were tested on each blood vessel in alternating order between ...
Table 1. Tm, ΔHm values, % of crystallinity, and tensile test results. According to the results presented in Table 1, in PHBV, rigidity and fragility were observed, which were characterized by the low deformation of the material, its sudden rupture, and the high elastic modulus. These pr...
