Effect of iron and ascorbic acid addition on dry infusion process and final color of pumpkin tissue [PDF]

, 2014
In the present study, pumpkin (Cucurbita moschata Duchesne ex Poiret) was used as raw material to produce sweet food fortified with iron (Fe) and ascorbic acid (AA). A dry infusion process with a subsequent air drying was applied.

The tissue distribution of L-ascorbic acid and dehydro-L-ascorbic acid in the guinea pigs injected intravenously with dehydro-L-ascorbic acid.

Journal of Nutritional Science and Vitaminology, 1986
The tissue distribution of L-ascorbic acid (AsA) and dehydro-L-ascorbic acid (DAsA) in guinea pigs injected with DAsA intravenously was examined using high-performance liquid chromatography. DAsA injected into guinea pigs fed normal diets containing AsA (control group) was readily taken into erythrocytes, and AsA contents of plasma and other tissues ...

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

Paracrine Factor Local Gradient‐Generating System for Engineering Perfusable Vascularized Hepatocyte Tissues with Perfusion‐Induced Proliferation

Advanced Healthcare Materials, EarlyView.
A paracrine factor local gradient (PFLG)‐generating system enables microvessel penetration across 3D hepatocyte tissues. The resulting vascularized constructs recapitulate hepatic sinusoidal hepatocyte—endothelial contact architecture and enhance hepatic functions in vitro.

Studies on L-Ascorbic Acid Derivatives. V. Hydrolysis of L-Ascorbic Acid 3-Phosphate

Chemical and Pharmaceutical Bulletin, 1971
The rate constants for the hydrolysis of L-ascorbic acid 3-phosphate were measured in aqueous solutions at 50-100° from pH 1 to 9.6 and also in strong acid solutions up to 4M hydrochloric acid. The first order kinetics with respect to the unreacted phosphate were obtained by determining the remaining phosphate. The pH rate profile (Fig.
