Ehrlich ascites tumor cell extracts form a gel when warmed to 25 degrees C at pH 7.0 in sucrose solution, and the gel rapidly becomes a sol when cooled to 0 degrees C. This gel-sol transformation was studied quantitatively by determining the volume or the total protein of pellets of gel obtained by low-speed centrifugation. The gelation depended on nucleotide triphosphates, Mg2+, KCl, and a red...

Silk fibroin (SF) is a typical fibrous protein that is secreted by silkworms and spiders. It has been used in a variety of areas, and especially for tissue-engineering scaffolds, due to its sound processability, mechanical properties, biodegradability, and biocompatibility. With respect to gelation, the SF gelation time is long in aqueous solutions, so a novel approach is needed to shorten this...

Noni (Morinda citrifolia L.) is one of the many herbs which known as an anticancer agent. Nanoencapsulated form noni extracts could help body absorption and able to inhibit proliferation cancer cells in vitro. This study was conducted examine activity nanoencapsulated vivo anti-proliferation agent cells. extract obtained by maceration method using water a solvent. The nanocapsule made ionic gel...

Biopolymers such as carrageenan or collagen can be used carriers for loading a drug to enhance drug’s bioavailability. In this work, allopurinol was loaded on carrageenan/collagen blend and the carrageenan/collagen/allopurinol (CCA) biocomposite films were prepared using ionic gelation method combined with 3D printing gel ink material. The advantages of are ease in shaping design controlling th...

Persea gratissima known as avocado is a valuable plant. P. (PgO) oil used in traditional medicine to treat several health problems because of its numerous biological properties. source phytosterols and has effects antimicrobial, anti-inflammatory, anti-oxidant neuroprotective activities for vitro vivo models. The aim this study synthesize characterize the PgO loaded chitosan nanoparticles inves...

high purity fluorapatite (fa) with rod-like and spherical-like morphology was synthesized via sol-gel method. chemical characterization of fa powders was done by xrd and ftir analyses. crystallite samples were calculated using scherer method. morphology of fa powders was investigated with tem and sem images. the results revealed that increasing the time of hydrolysis of phosphate sols significa...

Insulin therapy has been the best choice for the clinical management of diabetes mellitus. The current insulin therapy is via subcutaneous injection, which often fails to mimic the glucose homeostasis that occurs in normal individuals. Oral delivery is the most convenient administration route. However, insulin cannot be well absorbed orally because of its rapid enzymatic degradation in the gast...

Polymer composites consisted of small hydrophilic pockets homogeneously dispersed in a hydrophobic polymer matrix are important in many applications where controlled release of the functional agent from the hydrophilic phase is needed. As an example, a release of biomolecules or drugs from therapeutic formulations or release of salt in anti-icing application can be mentioned. Here, we report a ...

We have investigated the thermodynamic and dynamic behavior of multistranded β-lactoglobulin protein fibrils in water, by combining static, dynamic, and depolarized dynamic light scattering (SLS, DLS, DDLS), small angle neutron scattering (SANS), rheology, and cryogenic transmission electron microscopy (cryo-TEM). We focus on the region of the phase diagram at which ionic strength and concentra...
