The dipolar bonding mode is particularly dependent on the geometry and size of the antenna, allowing the incoupling cross section to be spectrally tuned and enhanced across a wide range of wavelengths. Enhancement suffers, however, if the resonance peak is redshifted too far into the NIR region. We also explored the effects of periodicity and incident angle on absorption and find that there is a trade-off between several different

resonant phenomena that can change both the spectral features and coupling efficiency of the geometry. (C) 2011 American Institute of Physics. [doi:10.1063/1.3587160]“
“Background: Pfizer Licensed Compound Library solubility dmso Pediculosis capitis is a highly transmissible infestation prevalent worldwide. It is an important public health problem mainly affecting children. The emergence of drug resistance and high rates of treatment failure with several topical agents makes ivermectin, an antiparasitic drug, an attractive therapeutic option for lice control.

Objective: To evaluate the efficacy and safety of oral ivermectin in the treatment of a pediatric population with pediculosis capitis.

Methods: Children with pediculosis capitis from the ages of 6 to 15 years were recruited from an indigenous community in Mexico, and were treated with a single dose of oral ivermectin at 200 mu g/kg. They were treated with selleck products a second dose of ivermectin

AZD2014 1 week later if there was evidence

of persistent infestation.

Results: Forty-four children (mean age, 9.8 years) with active infestation were treated. A single approximately 200-mu g/kg dose of ivermectin eradicated adult lice in all children. Forty-one percent (n = 18) required a second dose because of the presence of viable nits. At the third visit, 2 weeks after commencement of treatment there was no evidence of viable nits, and there was complete resolution of excoriations in all children and minimal or no symptoms of pruritus were reported in 93% (n = 41). There were no significant adverse effects due to ivermectin administration.

Conclusions: Ivermectin demonstrates high efficacy and tolerability in the treatment of pediculosis capitis in children. A significant number of children required a second dose to ensure complete eradication.”
“We calculated row resolved density of states, charge distribution and work function of graphene’s zigzag and armchair edge (either clean or terminated alternatively with H, O, or OH group). The zigzag edge saturated via OH group has the lowest work function of 3.76 eV, while the zigzag edge terminated via O has the highest work function of 7.74 eV. The angle-dependent potential barrier on the edge is fitted to a multipole model and is explained by the charge distribution. VC 2011 American Institute of Physics. [doi: 10.1063/1.
