The choroid is richly innervated by parasympathetic, sympathetic and trigeminal sensory
nerve fibers that regulate choroidal blood flow in birds and mammals, and presumably other …

The effects caused by exposure to lead (Pb) are still considered as a relevant health risk
despite public policies aimed to restricting the use of this element. The toxicity limit in the …

Metal oxide nanoparticles have a unique structure, interesting and unusual redox and
catalytic properties, high surface area, good mechanical stability and are biocompatible. For …

Calorie restriction (CR) enhances animal life span and prevents age-related diseases,
including neurological decline. Recent evidence suggests that a mechanism involved in CR …

Iron is essential for proper neuronal functioning; however, excessive accumulation of brain
iron is reported in Parkinson's, Alzheimer's, Huntington's diseases and amyotrophic lateral …

Epilepsy is characterized by a sustained depolarization and repeated discharge of neurons,
attributed to overstimulation of N-methyl-D-aspartate receptors (NMDAr). Herein, we …

Although neuronal nitric oxide synthase (nNOS) plays a substantial role in skeletal muscle
physiology, nNOS‐knockout mice manifest an only mild phenotypic malfunction in this …

Selective brain damage induced by ozone exposure. Ozone exposure induce superoxide
radical (O● 2) capable to produce an overproduction of proinflammatory markers as platelet …

Nitric oxide (NO) is associated with dopamine (DA) release. Previously, we demonstrated
that rats treated with a non-selective nitric oxide synthase inhibitor, N-omega-nitro-l-arginine …

Under pathological conditions, nitric oxide can become a mediator of oxidative cellular
damage, generating an unbalance between oxidant and antioxidant systems. The …
