SUMMARYA comparison has been made of the globulins, vicilin and legumin, prepared by isoelectric precipitation, of the seeds of three species of the Vicieae, namely Pisum sativum, Viciafaba and Cicer arietinum. Their amino acid composition, band patterns after electrophoresis upon polacrylamide-urea gels, fingerprint patterns of their tryptic digests and N-terminal amino acids were compared. Considerable portions of the amino acid sequences of vicilin and legumin of Pisum sativum are probably the same or very similar and both proteins consist of a number of sub-units. Viciafaba and Cicer arietinum also contain two proteins homologous with the vicilin and legumin of Pisum sativum. The homologous proteins of the three species resemble each other more closely than do the vicilin and legumin of any one species.

Soluble Ga/Ce-doped phosphate glass fibres exhibiting controlled release of ions were developed and characterised for wound healing applications. Fibres did not disturb the proliferation and migration of cells and showed antibacterial properties.

Phosphate-based glasses (PBG) have low melting temperatures and can be obtained by meltquenching and sol-gel methods. The most significant characteristic of PBG is their ability to dissolve completely in aqueous solution within different timeframes. This solubility can reduce the need for revision surgeries and makes PBG well-suited for soft tissue regeneration. Phosphate glass fibres (PGF) due to their geometry and volume-surface area ratio are the subject of a growing number of studies on resorbable composites. Medical applications include bone fixation devices, nerve tissue scaffolds and wound healing. PBG can be doped with various ions to enhance their biological, chemical and structural properties allowing the preparation of fibres with designed properties and with the ability to release biologically active ions upon degradation. The aim of this review is to look in detail at the influence of different dopants on PGF behaviour, both at a structural and biological level.

Due to their osteoconductive and osteoinductive abilities, bioglasses (BGs) have attracted attention in tissue engineering, especially for mineralized tissue. The aim of this study is to review the current state of the art on the effects of BGs produced by sol-gel on cells for dental and periodontal regeneration. The study also discusses associated antibacterial properties. The research was performed by considering the Preferred Reporting Items for Systematic Reviews and the Meta-Analyses (PRISMA) statement. The research ranged 5 years' window time (from January, 01, 2012, to August, 31, 2017) and the relevant studies were identified based on the inclusion/exclusion criteria. A total of 45 articles were selected from 244 initial returns, plus seven further articles coming from other sources were selected for the same purpose. From this systematic study, it is revealed that only 13 of the 52 articles have proved both the ability of BGs to differentiate dental cells at genetic level and their ability of triggering cell-mediated mineralization, but only six of them showed, along with cells, the antibacterial properties of the glasses. This review shows that sol-gel BGs are not toxic, can sustain cell proliferation and differentiation at a genetic level, and can keep the bacterial population under control. Moreover, a standard methodology and an ideal material are suggested. © 2018 Wiley Periodicals, Inc. J. Biomed. Mater. Res. Part B, 2018.
