Moreover, the cross-linked polymeric nanoparticles were highly active and selective catalysts for the cycloaddition reaction of carbon

dioxide to epoxides. The influences of reaction time, reaction temperature, CO2 pressure, and amount of catalyst on yield of the products were investigated. The results revealed that cyclic carbonates with high yield (98.4%) and selectivity (100%) could be produced on the condition of 0.1 g catalyst, 5 MPa CO2, 160 degrees C and 12 h. In addition, the nanocatalysts could be easily recovered by filtration, and reused several times with only slight loss of catalytic activity. (C) 2011 Wiley Periodicals, Inc.

“A 36-year-old woman with chronic psoriasis developed blurring of vision and intraepithelial infiltrates within the flap in the left eye Epigenetics inhibitor concurrent with the appearance of acute psoriatic generalized skin ISRIB cost lesions 14 days after bilateral laser in situ keratomileusis. After treatment with topical antibiotic and steroid agents and topical artificial tears, the intraepithelial infiltrates within the flap completely resolved. The final uncorrected distance visual acuity was 1.0 in both eyes, along with complete resolution of the dermatologic psoriatic lesions.”
“The mainstay of epilepsy surgery is the resection

of a presumed seizure focus or disruption of seizure propagation pathways. These approaches cannot be applied to all patients with medically refractory epilepsy (MRE). Since 1997, vagus nerve stimulation has been a palliative adjunct to the care of MRE patients. Deep brain stimulation (DBS) in select locations has been reported to reduce seizure frequency in small studies over the past three decades. Recently published results from the SANTE (Stimulation find more of the Anterior Nuclei of Thalamus for Epilepsy) trial-the first large-scale, randomized, double-blind trial of bilateral anterior thalamus DBS for MRE-demonstrate a significant reduction in seizure

frequency with programmed stimulation. Another surgical alternative is the RNS (TM) System (NeuroPace, Mountain View, CA), which uses a closed-loop system termed responsive neurostimulation to both detect apparent seizure onsets and deliver stimulation. Recently presented results from the RNS (TM) pivotal trial demonstrate a sustained reduction in seizure frequency with stimulation, although comprehensive trial results are pending.”
“A series of polymeric photoinitiators (BP-HPEAs) bearing BP moiety based on hyperbranched poly(ester-amine) were synthesized via the thiol-ene click reaction of 3-(4-benzoylphenoxy) propyl 2-mercaptoacetate (BPPM) with acrylated HPEA. BPPM was obtained by the esterification of (4-(3-hydroxypropoxy) phenyl) phenyl methanone (HPPM) with mercaptoacetic acid in the presence of p-toluene sulphonic acid as a catalyst.
