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...
Background and purpose: Adipose - drived stem cells are multipotent cells that capable to diffrentiate in to osteogenic cells. On the other hand, the scaffold of chitosan and gelatin are biodegradable and compatible used for tissue repair. This study evaluated the repair of femoral bone defect using adipose-derived stem cells on gelatin – chitosan membrane in adult Albino Wistar rats by radiog...
Mesoporous gold sponges were prepared using 4-dimethylaminopyridine (DMAP)-stabilized Au seeds. This is a general process, which involves a simple template-free method, room temperature reduction of HAuCl4·4H2O with hydroxylamine. The formation process of mesoporous gold sponges could be accounted for the electrostatic interaction (the small Au nanoparticles (~3 nm) and the positively charged D...
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...
This review article presents our group’s recent research findings with regard to bioactive natural products from marine sponges and tunicates, as well as from spongederived fungi. The organisms discussed originate in the Indopacific region, which has an exceptionally rich marine biodiversity. Major topics that are covered in our review include the chemical ecology of sponges, focusing on defens...
The sterol and fatty acid composition of three Adriatic Sea sponges (Geodia cydonium and two unidentified Tedania sp.), collected at the same time and same place, was established. Twenty-four sterols and forty fatty acids were identified. The identical ecological conditions, including the diet, allowed us to apply the results obtained for taxonomical conclusions, based on the biodiversity of th...
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...
