“A pair of solvatochromic phenolate betaines that differed only in their lipophilicity was synthesized. Their solvatochromic responses in pure solvents, in a DMSO-MeOH solvent mixture as well as in micellar solutions were different, an observation which confirmed the fact that sensor lipophilicity contributes to the interpretation of solvatochromism. Quantum mechanical calculations reproduced the observed spectral differences. Molecular dynamics simulations shed light on the solute-solvent interactions responsible for their differences in solvent mixtures. (C) 2009

“The weaver ant, Oecophylla smaragdina (Hymenoptera: Formicidae), is a successful predator and repellent of a range of insect pests of many economically important AZD6094 cost crops and forest trees. To use the ant as a biocontrol agent, extension officers and farmers need to know the best time of day to identify and transplant
the ant colonies and to measure the abundance of the ant. To answer these questions, it is important to know about ant activity over a 24-h period at the colony level. Ant activities of three weaver ant colonies on the Tiwi campus of Charles Darwin University, Darwin, were measured in both dry and wet seasons in 1997 and 1998. The activity patterns on three types of ant trails learn more showed that ants were least active between the hours of 10:30 and 14:00, and their activity peaked between 16:00 and 21:00 h. There was also a smaller activity peak from 8:00 to 9:00 h. The best time of day to identify ant colonies and to measure ant abundance is from 16:00 to 21:00 h (late afternoon to dusk). The best time to transplant weaver ant colonies find more is between 10:30 and 14:00 h (midday).”
“Since randomized controlled trials are difficult to perform for ethical reasons in a potentially deadly condition like status epilepticus (SE), a retrospective database analysis may be welcome to broaden the evidence for the treatment of SE. In this retrospective study we evaluated every SE treatment at the neurological department
of the University of Rostock from January 2000 to December 2009 in order to determine the efficacy of different antiepileptic drugs (AEDs) in terminating different kinds of SE. We analyzed the frequency of refractory courses in different types of SE, at which time which AED was administered and at which time which AED was effective to terminate the different epileptic conditions. A second aim of this study was to evaluate the course and the outcome of different kinds of SE. Statistical comparisons were performed with the x(2)-test. 167 episodes of SE in 118 patients could be evaluated. The efficacy rates of AEDs differed significantly, mainly due to the superior efficacy of clonazepam (CZP).
