Anisotropic discs loaded by parabolically distributed pressure

Rapid calcium release by passively loaded retinal discs on photoexcitation.

In vertebrate retinal rods, rhodopsin undergoes a conformational change upon absorption of a quantum of light. The primary photoprocess is followed by a transient depolarisation of the outer receptor membrane. It is generally accepted that the depolarisation is due to the closing of Na’channels [l-4]. As the rhodopsin containing inner discs and the plasma membrane of the retinal rods seem to be...

Preparation of Gentamicin Loaded PLGA Discs

This paper reports the fabrication of drug-loaded microspheres by the spray drying method. The microspheres are then compressed by a hydraulic hand press and a die into a disc. The characterization of the microspheres and the effects of different drug loading percentage on the release profile of the drug from the disc are investigated. The effects of different types of polymers used for the fab...

Anisotropic X-ray emission in AGN accretion discs

Straight-forward models of X-ray reflection in the inner region of accretion discs predict that primary X-ray flux and the flux reflected off the surface of the disc should vary together, albeit a short light travel time delay. Most of the observations, however, show that the X-ray flux can vary while the reflected features remain constant. Here we propose a simple explanation to this. In all l...
