Crystalline structure analysis of cellulose treated with sodium hydroxide and carbon dioxide by means of X-ray diffraction and FTIR spectroscopy.
Crystalline structures of cellulose (named as Cell 1), NaOH-treated cellulose (Cell 2), and subsequent CO2-treated cellulose (Cell 2-C) were analyzed by wide-angle X-ray diffraction and FTIR… Expand

Tumor cells interact with endothelial cells during both intraand extravasation. Understanding how these interactions are modulated could lead to the development of ways to alter the metastatic… Expand
The effect of type II collagen coating of chitosan fibrous scaffolds on mesenchymal stem cell adhesion and chondrogenesis.
The biocompatibility of chitosan and its similarity to glycosaminoglycans (GAG) make it attractive for cartilage tissue engineering. We have previously reported improved chondrogenesis but limited… Expand
Effect of growth and sodium butyrate on brush border membrane-associated hydrolases in human colorectal cancer cell lines.
The activities of brush border membrane-associated hydrolases such as alkaline phosphatase (Alkpase), aminopeptidase, dipeptidyl aminopeptidase IV (DAP-IV), sucrase, lactase, and trehalase were… Expand

Certain alterations of blood group substance (BGS) expression have been observed in gastrointestinal cancer tissues. However, in the pancreas little is known about BGS expression by normal or… Expand
Effect of N-acylation on structure and properties of chitosan fibers
This article described the physico-chemical transition of the chitosan fibers by N-acylation. N-Acyl chitosan fibers were prepared by a post-treatment of chitosan fibers with carboxylic anhydrides… Expand
Ruthenium recovery from acetic acid waste water through sorption with bacterial biosorbent fibers.
A fibrous bacterial biosorbent was developed to bind precious metal-organic complexes in batch and column processes. Polyethylenimine (PEI)-modified bacterial biosorbent fiber (PBBF) was prepared by… Expand

Although numerous biomaterials have been investigated as scaffolds for cartilage tissue engineering, the effect of their microstructure on final construct characteristics remains unclear. The… Expand
Recovery of gold as a type of porous fiber by using biosorption followed by incineration.
This study introduces a new process for the recovery of gold in porous fiber form by the incineration of Au-loaded biosorbent fiber from gold-cyanide solutions. For the recovery of gold from such… Expand
Characteristics of ultrasonic dyeing on poly(ethylene terephthalate)
The influence of ultrasound on the dyeing behavior of PET fibers is investigated using a disperse dye. Ultrasound, when used with a dyebath, enhances the dye uptake and dyeing rate for C.I. Dispers...
