Pulsed electric field (PEF) and/or mild thermal (60 °C) processing distinctly affect the texture degradation of carrot tissues during subsequent cooking. The impact PEF on texture-related pectin properties was studied in terms extractability, degree methylesterification (DM) and Ca 2+ crosslinking cortex vascular tissue. In case tissue, treatments significantly (? = 0.05) reduced extractability...

Alginate is a natural polysaccharide exhibiting excellent biocompatibility and biodegradability, having many different applications in the field of biomedicine. Alginate is readily processable for applicable three-dimensional scaffolding materials such as hydrogels, microspheres, microcapsules, sponges, foams and fibers. Alginate-based biomaterials can be utilized as drug delivery systems and c...

~emistry of the crosslinking of gelatin is a complex phenomenon. the nature of which is dependent on several factors. The present manuscript represents an attempt to answer some specific basic science issues. Two "stress" conditions are commonly known in connection with gelatin capsules. The first condition is induced by exposure to formaldehyde. The second stress condition is created by exposi...

Starch is a carbohydrate composed of chain of glucose molecule. Potato, corn, rice are the major sources for starch but they are also used as a food. Our aim was to extract starch from some nonconventional source like taro plant (Colocasia esculenta) and did some physical and chemical modification to enhance the properties of starch. Physical modification method of starch like Osmotic Pressure ...

A new synthetic approach to the preparation of intramolecularly collapsed nanoparticles under mild, room temperature conditions has been developed from commercially available vinyl monomers. Reaction of isocyanate functionalized linear copolymers with a diamine in dilute solution leads to the efficient formation of nanoparticles where the diameter of the nanoparticle can be varied by controllin...

Transport of vitamin B(12) across the outer membrane of Escherichia coli, like that of iron-siderophore complexes, is an active transport process requiring a specific outer membrane transporter BtuB, the proton motive force, and the trans-periplasmic energy coupling protein TonB. Interaction between TonB and two of the TonB-dependent siderophore transporters has been detected previously by form...

Glucosamine (GlcN) fulfills many of the requirements as an ideal component in scaffolds used in cartilage tissue engineering. The incorporation of GlcN in a gelatin/hyaluronic acid (GH) cryogel scaffold could provide biological cues in maintaining the phenotype of chondrocytes. Nonetheless, substituting gelatin with GlcN may also decrease the crosslinking density and modulate the mechanical pro...

PURPOSE To report a keratoconic eye that developed severe sterile keratitis and corneal scar after collagen crosslinking necessitating corneal transplantation. CASE REPORT A 26-year-old man with progressive keratoconus underwent collagen crosslinking and presented with severe keratitis 72 hours after the procedure. The initial impression was infectious corneal ulcer and a fortified antibiotic...
