Bioactive tricalcium silicate/alginate composite bone cements with enhanced physicochemical properties.

Chen Xu et al.

Journal of biomedical materials research. Part B, Applied biomaterials, 106(1), 237-244 (2017-01-29)

Previous studies have shown that tricalcium silicate bone cements possess good bioactivity and appropriate degradation rate. However, they also showed some weaknesses such as poor washout resistance, formability and injectability, which have seriously hindered their clinical applications. The purpose of

Rheological Properties of Fish Gelatin Modified with Sodium Alginate.

Svetlana R Derkach et al.

Polymers, 13(5), 743-743 (2021-03-07)

Polyelectrolyte complexes of sodium alginate and gelatin obtained from cold-blooded fish were studied for potential application as structure-forming agents in food hydrogels. The mass ratio of sodium alginate to gelatin plays a decisive role in the sol-gel transition and rheological

Effect of alginate encapsulation on the cellular transcriptome of human islets.

Vijayaganapathy Vaithilingam et al.

Biomaterials, 32(33), 8416-8425 (2011-09-06)

Encapsulation of human islets may prevent their immune rejection when transplanted into diabetic recipients. To assist in understanding why clinical outcomes with encapsulated islets were not ideal, we examined the effect of encapsulation on their global gene (mRNA) and selected

Should we isolate human preantral follicles before or after cryopreservation of ovarian tissue?

Julie Vanacker et al.

Fertility and sterility, 99(5), 1363-1368 (2013-02-05)

To evaluate the survival and growth potential of human preantral follicles isolated before and after cryopreservation. Pilot study. Gynecology research unit in a university hospital. Six women aged 27 to 32 years. Six ovarian biopsy samples were cut into two

Aggregation and deposition kinetics of carboxymethyl cellulose-modified zero-valent iron nanoparticles in porous media.

Trishikhi Raychoudhury et al.

Water research, 46(6), 1735-1744 (2012-01-17)

Transport and deposition of carboxymethyl cellulose (CMC)-modified nanoparticles of zero-valent iron (NZVI) were investigated in laboratory-scale sand packed columns. Aggregation resulted in a change in the particle size distribution (PSD) with time, and the changes in average particle size were
