A new microencapsulation technique that utilizes interfacial mass transfer between two mutually soluble liquids has been developed. The technique is based on formation of a solid polymer film at the interface of a solution of a water-insoluble polymer and an aqueous solution, resulting from the mutual mass transfer of solvents (i.e., solvent exchange). Reservoir-type microcapsules were prepared...

PURPOSE To assess the ability of trabecular micro-bypass stents to improve aqueous humor outflow (AHO) in regions initially devoid of AHO as assessed by aqueous angiography. METHODS Enucleated human eyes (14 total from 7 males and 3 females [ages 52-84]) were obtained from an eye bank within 48 hours of death. Eyes were oriented by inferior oblique insertion, and aqueous angiography was perfo...

A sample treatment method based on an aqueous two-phase system containing polyethylene glycol and dextran was developed for enhancing sensitivity in the detection of Listeria monocytogenes in soft cheese with PCR. The results suggest that the improved detection sensitivity following partitioning of the cheese homogenate in an aqueous two-phase system may be due to partitioning of the PCR inhibi...

A high-pressure system incorporating an optical cell and suitable for the study of aqueous biological systems is described. The high-pressure system can be assembled from commercially available components. Using the system gas pressures up to 70 MPa of various gases can be generated from pressures available in the laboratory and maintained over samples for extended periods of time. Preliminary ...

AIM To assess the incidence of anterior chamber bacterial contamination during phacoemulsification surgery using an automated microbial detection system (BacT/Alert). METHODS Sixty-nine eyes of 60 patients who had uneventful phacoemulsification surgery, enrolled in this prospective study. No prophylactic topical or systemic antibiotics were used before surgery. After antisepsis with povidone-...

A conservative CO2-Methanol (CH3OH) regeneration cycle, to capture and reutilize the greenhouse gas of CO2 by aqueous hydrogenation for industry-useful CH3OH and to convert aqueous CH3OH solution by dehydrogenation for the clean energy of hydrogen (H2), is demonstrated at normal temperature and pressure (NTP) with two kinds of CuMnOS nanoflower catalysts. The [Cu+]-high CuMnOS led to a CH3OH yi...

The authors examined how certain humor styles mediate the relations between self-evaluative standards (which form the primary evaluative component of the self-schema) and psychological well-being. As predicted, greater endorsement of positive self-evaluative standards led to the use of more affiliative humor, which, in turn, led to higher levels of social self-esteem and lower levels of depress...

ordered mesoporous carbon cmk-3 (omc) have been synthesized using mesoporous sba-15 silica as template and modified with cobalt carbonate. morphologies and surface texturing of materials werecharacterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and n2 adsorption-desorptionisotherms. the cobalt modified ordered mesoporous carbon were found to have a surface area of 490.06m...

[2-H] Myoinositol accumidates in rabbit ciliary body-iris preparations in vitro against a concentration gradient. The transport system is energy and temperature dependent (Ql0 = 2.3) and demonstrates saturation kinetics (Km = 0.9 mM.). It is inhibited by ouabain, iodoacetate, phlorhizin, and shows requirements for Na, K+, and Ca. The transport system appears highly specific; various amino acids...

We report the design and the electrical and microfluidic characterization of a device that improves signal strength and increases the detection levels in microfluidic impedance cytometry. Low-conductivity aqueous and two-phase dielectric sheathing allows the use of wider, more easily fabricated channels, increases the precision of celland particle-size measurements, and decreases the smallest d...
