We developed a n-hexane/surfactant-containing water solvent system in counter-current chromatography (CCC) in order to separate hydrophobic compounds. By using the upper phase as the mobile phase, we have separated steroid samples. Retention times of steroids progesterone and delta4-androstene-3,17-dione increased slightly by increasing the concentration below the critical micellar concentratio...

A consistent finding in computer-mediated communication (CMC) and Internet research is that, compared to face-toface communication, CMC results in higher levels of self-disclosure. We identified four possible mediators that may carry the influence of CMC on self-disclosure: self-presentation, similarity, self-awareness, and direct questioning. The validity of these mediators was tested in an ex...

Achieving oriented and ordered remineralization on the surface of demineralized dental enamel, thereby restoring the satisfactory mechanical properties approaching those of sound enamel, is still a challenge for dentists. To mimic the natural biomineralization approach for enamel remineralization, the biological process of enamel development proteins, such as amelogenin, was simulated in this s...

Medicinal carbon (MC) tablets were prepared to obtain an oral dosage form that can be easily taken. The MC tablets were made by the wet granule compression method, in which hydroxypropyl cellulose (HPC), carboxymethyl cellulose sodium (CMC-Na) and maltitol (MT) were applied as binders. Brilliant Blue FCF (BB) was used as a model drug. The binders were evaluated in terms of formability of the gr...

Changes in the tertiary structure of proteins and the resultant fibrillary aggregation could result in fatal heredity diseases, such as lysozyme systemic amyloidosis. Human lysozyme is a globular protein with antimicrobial properties with tendencies to fibrillate and hence is known as a fibril-forming protein. Therefore, its behavior under different ambient conditions is of great importance. In...

The effects of the non-ionic surfactant Triton X-100, the cationic surfactant cetyltri-methylammonium bromide (CTAB) and the anionic surfactant sodium N-lauroyl sarcosinate (SLS) on the decolorization of the reaction medium containing the monoazo dye Acid Orange 7 (AO7) by Alcaligenes faecalis and Rhodococcus erythropolis were studied. It was found that the surfactants influenced in different w...

The bottleneck in the implementation of hybrid lithium-sodium-ion batteries is lack anode materials with a desired rate capability. Herein, we provide an in-depth examination Li-storage performance sodium titanate nanowires as negative electrodes Li,Na-ion batteries. Titanate were prepared by simple and reproducible hydrothermal method. At low reaction pressure, well-isolated are formed, while ...

Mutant mice of mi/mi genotype are osteopetrotic and deficient in tissue mast cells due to a defect in osteoclasts and mast cells. In an effort to further understand the mechanisms behind why mi/mi mouse-derived cultured mast cells (mi/mi-CMC) responded to interleukin-3 (IL-3), but not to the proliferative stimuli presented by fibroblasts, mi/mi-CMC and congenic normal (+/+) mouse-derived CMC (+...

In the present study, silver nanoparticles (AgNPs) were synthesized via biological reduction of silver nitrate using extract of the fungus Fusarium verticillioides (green chemistry principle). The synthesized nanoparticles were spherical and homogenous in size. AgNPs were coated with polyethylene glycol (PEG) 6000, sodium dodecyl sulfate (SDS), and β-cyclodextrin (β-CD). The averaged diameters ...

This study investigated the use of cotton linter fiber as a raw material for manufacturing carboxymethylated cellulose nanofiber (CM-CNF). Cotton mixed pulp (CLMP) and hardwood bleached kraft (HwBKP) were used preparing carboxymethlyated (CMC) based on degree carboxymethylation (CM) considering dosage sodium hydroxide: monochloroacetic acid: low high CMs. After CM reactions, we evaluated length...
