The objective of this study was to assess whether carboxymethyl cellulose- (CMC-) based hydrogel containing BioC (biphasic calcium phosphate (BCP); tricalcium phosphate (TCP) : hydroxyapatite (Hap) = 70 : 30) and bone morphogenic protein-2 (BMP-2) led to greater bone formation than CMC-based hydrogel containing BioC without BMP-2. In order to demonstrate bone formation at 4 and 8 weeks, plain r...

To evaluate the sedimentation of aluminium phosphate [AlPO4] and ferrous [Fe3(PO4)2] precipitates in sodium carboxymethylcellulose (Na-CMC) biopolymer at different temperatures, batch-wise precipitation tests AlPO4 Fe3(PO4)2 solutions Na-CMC were carried out temperatures 30, 40 50oC. The objective was to determine On-set Sedimentation Rate (OSR) Volume Ratio (SVR) metal phosphates. Fixed volume...

The influence of surfactant hydrocarbon tail on the solute/pseudostationary phase interactions was examined. Four anionic sulfated surfactants with 8-, 9-, 10-, and 11-carbon chains having a polymerizable double bond at the end of the hydrocarbon chain were synthesized and characterized before and after polymerization. The critical micelle concentration (CMC), polarity, and aggregation number o...

The surface potential (DeltaV) of the air/sodium chloride solution interface was measured by using an ionizing (241)Am electrode method at 298.2 K. The surface potential steeply increased from 0 up to 15 mV with increasing concentration, then gradually increased up to 20 mV between 1 and 10 mmol dm(-3), and finally stayed almost constant at 20 mV up to the concentration of 20 mmol dm(-3). This ...

This study integrates the literature on computer anxiety and communication apprehension to determine their joint impact upon individual attitudes toward using and use of computer mediated communication (CMC). We introduce the application-specific CMC anxiety, defined as an individual’s level of fear or apprehension associated with actual or anticipated use of information technology to communica...

BACKGROUND For patients who experience dry eye after phacoemulsification, vision and quality of life can significantly deteriorate. In this study, the efficacy and safety of carboxymethylcellulose sodium (CMC) 1% ophthalmic solution combined with conventional therapy in treating dry eye signs and symptoms after phacoemulsification were evaluated. METHODS In this prospective, multicenter, open...
