Induced osteogenesis by chitosan (3-glycidoxypropyl)trimethoxysilane and silica based biomaterial in rabbits.

Introduction: Synthetic biomaterials obtained through tissue engineering offer an alternative to the use of autologous and heterologous grafts for the repair of bone defects of various etiologies, although the ideal material for this purpose has not yet been developed. A gel based on Chitosan (CS) ((3-glycidoxypropyl)trimethoxysilane (GPTMS), and silica have shown efficacy in experimental studies from a biomechanical and in vitro osseointegration perspective.

Objective: To demonstrate that the hybrid aerogel based on CS-GPTMS-silica is effective and safe for treating bone defects in load-bearing bone in rabbits.

Using uniparental genetic profiles to unravel the complexity of Argentine admixed populations.

Latin American countries are distinguished by their highly admixed populations, characterized by a significant preservation of Native American matrilineal ancestry. This contrasts with the paternal lineages, which exhibit different patterns due to pronounced sex-biased mating practices during the colonial period. Uniparental genetic markers have been instrumental in population genetics, facilitating the reconstruction of human settlement histories and serving forensic identification purposes.

Optimizing Screw Speed and Barrel Temperature for Textural and Nutritional Improvement of Soy-Based High-Moisture Extrudates.

Soy remains the legume protein of excellence for plant-based meat alternatives due to its fiber-forming potential. In this study, protein-rich powders from soy protein isolate (SPI), concentrate (SPC), and their mixture (SPM) were thoroughly characterized for their proximate composition, nutritional quality, and physicochemical properties to understand their structuring behavior during high-moisture extrusion. SPI presented higher degrees of protein denaturation and aggregation, least gelation concentration and lower essential amino acid contents.

Biofortification and Valorization of Celery byproducts Using Selenium and PGPB under Reduced Nitrogen Regimes.

Due to climate change and exacerbated population growth, the search for new sustainable strategies that allow for greater food productivity and that provide greater nutritional quality has become imperative. One strategy for addressing this problem is the combined use of fertilization with a reduced dose of nitrogen and biostimulants. Celery processing produces a large amount of waste with its concomitant pollution.
