1. In pure gelatin solutions the conductivity of the solution increases with increasing concentrations, regardless of the hydrogen ion concentration. The actual value of the specific conductivity is greater at that reaction where the degree of ionization is greater. 2. The addition of gelatin in increasing concentrations to a 0.6 per cent sodium chloride solution affects the conductivity of tha...

The efficacy of gelatin for the recovery of Neisseria meningitidis from blood cultures was evaluated in a clinical setting. The organism was isolated from seven patients with meningococcal infections in blood culture media containing 1% gelatin. In contrast, only two blood cultures from these patients were positive in media without gelatin (P less than 0.05). Gelatin did not influence the recov...

Gelatin given by vein to doubly depleted dogs (anemic and hypoproteinemic) gives no immediate toxic response, no anaphylactoid reactions, and may contribute something to the building of new hemoglobin and plasma protein. Gelatin given by vein during 1 to 2 weeks (total 3 to 17 gm. per kilo) usually causes serious disturbances-inhibition of blood protein production, signs of intoxication, much w...

In order to develop a systemically administered safe and effective nonviral gene delivery system, cellular interactions and plasmid DNA transfection with poly(ethylene glycol)-modified (PEGylated) gelatin nanoparticles were examined. The DNA-containing nanoparticles were prepared by a controlled water-ethanol solvent displacement method. The nanoparticles were characterized for particle size, s...

Demand of gelatin for food and pharmaceutical application is increasing because it is one of the most widely used food ingredients. Fish gelatin represents one of the important types of gelatin from other sources other than mammalian gelatins and it may thus be considered as an alternative to mammalian gelatin for use in various food and pharmaceutical applications. The main objective of the st...

We report a simple, effective and green way for the fabrication of gelatin-graphene-like BN nanocomposites for gas barrier applications. The reinforcement effect of graphene-like BN on the gelatin properties is discussed. The obtained graphene-like BN nanocomposites show good dispersion in the gelatin matrix and remarkable capability to improve the crystallinity and the barrier properties of ge...

In the preceding paper it was shown that the attachment of tyrosine, tryptophan or phenylalanine peptides to gelatin converts it into a relatively powerful antigen. The serological specificity of these gelatin derivatives varied according to the nature and the length of the peptides attached. Thus the specificity of polytyrosyl gelatin (10% of tyrosine residues) and polytryptophyl gelatin (25% ...

This study was conducted to determine the effect of duck feet gelatin concentration on the physicochemical, textural and sensory properties of duck meat jellies. Duck feet gelatin was prepared with acidic swelling and hot water extraction. In this study, four duck meat jellies were formulated with 3, 4, 5, and 6% duck feet gelatin, respectively. In the preliminary experiment, the increase in du...

Most users of ordnance gelatin for ballistics studies are apparently unaware of the detrimental effects on this tissue simulant's properties caused by excess heating in reconstitution of the gelatin powder. Material published by the Gelatin Manufacturers Institute of America states that heating gelatin above 40 degrees C can be detrimental to its properties. The manufacturer of type 250 A Ordna...
