For neuroprosthetic use of afferent activity, model results and experimental recordings of action potentials (ap's) made with Tungsten micro electrodes in rat peronedsural nerve are presented and compared. The model shows that the normal shape can be as well biphasic as triphasic, depending on extraneural conductivity. In the experiments, five classes of ap shapes are observed, of which two are...

Angiomyolipoma an uncommon benign neoplasm of the kidney is a triphasic tumour composed of angiomatous, smooth muscle and adipose tissue elements. They are usually associated with Tuberous sclerosis and commonly bilateral in presentation .Angiomyolipoma is often asymptomatic and is dedected incidentally in radiological studies and during autopsies. We present a rare case of a giant renal angiom...

Guanidine has been used with some success to treat myasthenia gravis and myasthenic syndrome because it increases acetylcholine release at nerve terminals through K⁺, Na⁺ and Ca²⁺ channels-involving mechanisms. Currently, guanidine derivatives have been proposed for treatment of several diseases. Studies aimed at providing new insights to the drug are relevant. Experimentally, guanidine (10 mM)...
