The functional analysis of neuronal circuitry would be facilitated if researchers were able to control, over extended periods of time, the activity of genetically defined populations of neurons in vivo. New work using light-gated cation channels from green algae offers hope that this might soon be possible.

The first proof of concept for the application of intragel green-to-blue photon upconversion to a chemical reaction is reported. The developed method allows the photoreduction of aryl halides at room temperature under aerobic conditions.

The high energy limit of scattering amplitudes in the N = 4 supersymmetric Yang– Mills theory is studied by solving the corresponding BFKL equation in the next– to–leading approximation. The gluon Green’s function is analysed using a newly proposed method suitable for investigating the contribution from higher conformal spins. From this new approach complete agreement is obtained with the resul...

Emission and absorption properties of indocyanine green (ICG) in Intralipid solution have been investigated. The study is focused on relatively low ICG concentration at a range of 0 to 20 microM. A diffusion model was used to analyze the emission properties of ICG solution at different concentrations. In the low-concentration region, the emission strength increases with the concentration of ICG...

111 25 per cent, of cases may be due to excess of Proteins in the food. Not only this?irregularity in the time and duration of the feeds and sometimes uncleanly habits of the mother, also act as contributory factors. But in niy opinion, based on some recent investigations 011 youngrabbits there is another paramount factor in the etiology of the disease: this is deficiency of the growthproducing...
