Local supra-linear summation of excitatory inputs occurring in pyramidal cell dendrites, the so-called dendritic spikes, results in independent spiking dendritic sub-units, which turn pyramidal neurons into two-layer neural networks capable of computing linearly non-separable functions, such as the exclusive OR. Other neuron classes, such as interneurons, may possess only a few independent dend...

Local anaesthesia for eye surgery is usually safe, but serious complications may sometimes occur. Sharp-needle blocks (retrobulbar or peribulbar) can potentially cause blindness or even death. Sub-Tenon's blocks, using a blunt-ended cannula, appear to be much safer. However, they can also cause serious complications. Sharp-needle techniques (retrobulbar and peribulbar injections) These appear t...

niosomes are non-ionic surfactant vesicles that have potential applications in the delivery of hydrophilic and hydrophobic drugs. the topical form of n-acetyl glucosamine (nag) recently has been considered in the treatment of hyperpigmentation disorders due to its inhibitory effect on thyrosinase enzymes in melanocytes. to improve nag penetration into the skin we formulated the drug in niosomes...

pterygium is characterized by an elastic degeneration of the conjunctiva that extends across the limbos and invades the cornea. the recurrence rate is varied from 25-80% after primary closure to 6% with free conjunctival and iimbal grafts. several adjunctive therapies have been investigated for recurrent pte¬rygium. this article presents a 52-year-old athletic man who was seen for evaluation of...
