The aim of this study was to evaluate the acute lung toxicity of intratracheally instilled single-wall
carbon nanotubes (SWCNT) in rats. The lungs of rats were instilled either with 1 or 5 mg/…

Previous studies have reported little correlation between the relative toxicity of particle types
when comparing lung toxicity rankings following in vivo instillation versus in vitro cell culture …

Surface properties are critical to assess effects of ultrafine-TiO 2 particles. The aim of this
study was to assess lung toxicity in rats of newly developed, well characterized, ultrafine-TiO 2 …

Local anesthetics have an impressive history of efficacy and safety in medical and dental
practice. Their use is so routine, and adverse effects are so infrequent, that providers may …

Pulmonary toxicology studies in rats demonstrate that nanoparticles administered to the
lung are more toxic than larger, fine-sized particles of similar chemistry at identical mass …

The development of a risk management system for nanoscale or ultrafine particle-types
requires a base set of hazard data. Assessing risk is a function of hazard and exposure data. …

Objective. To present a novel approach for treatment of intractable occipital neuralgia using
percutaneous peripheral nerve electrostimulation techniques. Methods. Thirteen patients …

To study the effects of amitriptyline in treating postherpetic neuralgia, 24 patients were randomly
assigned to either drug or placebo in a double-blind crossover study. We found good to …

It is impossible to provide effective dental care without the use of local anesthetics. This
drug class has an impressive history of safety and efficacy, but all local anesthetics have the …

The field of nanotechnology currently is undergoing a dramatic expansion in material science
research and development. Most of the research efforts have been focused on applications…
