In this work, the physicochemical properties and in vitro bioactivity and cellular viability of two commercially available bovine bone blocks (allografts materials) with different fabrication processes (sintered and not) used for bone reconstruction were evaluated in order to study the effect of the microstructure in the in vitro behavior. Scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectrometry, mechanical resistance of blocks, mercury porosimetry analysis, in vitro bioactivity, and cell viability and proliferation were performed to compare the characteristics of both allograft materials against a synthetic calcium phosphate block used as a negative control. The herein presented results revealed a very dense structure of the low-porosity bovine bone blocks, which conferred the materials’ high resistance. Moreover, relatively low gas, fluid intrusion, and cell adhesion were observed in both the tested materials. The structural characteristics and physicochemical properties of both ceramic blocks (sintered and not) were similar. Finally, the bioactivity, biodegradability, and also the viability and proliferation of the cells was directly related to the physicochemical properties of the scaffolds.

Abstract Background: Spikelets at different spike positions and the caryopsis at different grain positions grow and develop differently. The caryopsis development and physicochemical properties of starch at different grain positions (the first, second, and third grain positions: G1, G2, and G3) of wheat spikelets were investigated in this study. Results: During the development process, the thickness of both dorsal and abdomen pericarp 8 days after anthesis (DAA) followed the sequence G2 < G1 < G3. However, at 14 DAA the thickness followed the dorsal sequence of G1 < G2 < G3 and the abdomen sequence of G2 < G1 < G3. At 20 and 30 DAA, no difference existed in the pericarp thickness of each grain. The accumulation quantities before 20 DAA varied with starch and protein of endosperm cell in the order G1 > G2 > G3. In mature caryopsis, the caryopsis size and weight indicate that G1 = G2 > G3. The starch content followed the order G1 > G2 > G3, while the essential amino acid, the total amino acid, and the protein content followed the order G2 > G1 > G3. The apparent amylose content followed the sequence G3 > G2 > G1, and A-type starch content followed G3 > G1 > G2. The amorphous ratio followed the order G2 > G1 > G3, whereas the double-helix ratio and the relative crystallinity exhibited the opposite trend. The order of the final degree of hydrolysis through AAG, PPA, and HCL was G2 > G1 > G3. Conclusions: The different material contents were possibly due to the short development time of caryopsis, and the difference in starch physicochemical properties between G2 and the other grain positions might be related to the components and structural characteristics of starch.
