The aim of this study was to entrap the lipophilic ultraviolet absorber, octyl methoxycinnamate in microcapsuels to enhance its application. A complex coacervation method was established. Through the appearance of encapsulated glass beads prepared with different wall materials, gelatin and sodium polyphosphate were selected as wall materials because of dense structure and less adhesion. The eff...

Reproductive competition in social insects is generally mediated through specific fertility pheromones. By analysing Dufour's gland secretion in queens and workers of Bombus terrestris under varying social conditions, we demonstrate here that the volatile constituents of the secretion exhibit a context-dependent composition. The secretion of egg-laying queens is composed of a series of aliphati...

OBJECTIVE To compare the surgical efficacy and wound-healing characteristics of the tissue adhesive octyl-2-cyanoacrylate (approved by the Food and Drug Administration) with traditional suture closure in upper blepharoplasty. METHODS Prospective, randomized, blinded study comparing cosmetic and functional outcome and time efficiency. Twenty subjects underwent upper eyelid blepharoplasty. Each...

The volume change and sorption of CO2 of ionic liquids(ILs) were measured in a high pressure view cell under supercritical fluid condition. Imidazolium-based ILs such as 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]), 1-butyl-3-methyl-imidazolium tetrafluoroborate ([bmim][BF4]), and 1-octyl-3-methylimidazolium tetrafluoroborate ([omim][BF ]) were employed in this research. The ef...

Plasma membrane preparations partially inhibit the reaggregation of dissociated aggregation-component cells of Dictyostelium discoideum, and membranes from aggregation-competent cells are more inhibitory than membranes from vegetative cells. Inhibitory activity can be extracted from the membranes of aggregation-competent cells with the detergent octyl glucoside or with EDTA, although the inhibi...

Since that time, new data have become available, and these have been incorporated into the monograph and taken into consideration in the present evaluation. Chem. Abstr. Name: 1,2-Benzenedicarboxylic acid, bis(2-ethylhexyl) ester IUPAC Systematic Names: Bis(2-ethylhexyl) phthalate; phthalic acid, bis(2-ethyl-hexyl) ester Synonyms: Bis(2-ethylhexyl) 1,2-benzenedicarboxylate; bis(2-ethylhexyl) or...

Environmental impacts caused by tin and copper based commercial antifouling (AF) paints were proved to be detrimental to aquatic ecosystems. Therefore, a search of environmental friendly AF compounds to be used in marine paint to protect the surface of maritime developmental structures from the unwanted biofouling is a burning issue of the present time. Commercially available eight organic chem...

In this study, N,N-Dimethyl-N-Octyl chitosan was synthesized. Nanoparticles containing insulin were prepared using PEC method and were statistically optimized using the Box-Behnken response surface methodology. The independent factors were considered to be the insulin concentration, concentration and pH of the polymer solution, while the dependent factors were characterized as the size, zeta po...
