Identification And Quantification

A methodology has been developed and demonstrated which is capable of determining total amounts of asbestos fibers and fibrils in air ranging from as low as fractional nanograms per cubic meter (ng/m3) of air to several micrograms/m3. The method involves the collection of samples on an absolute filter and provides an unequivocal identification and quantification of the total asbestos contents including fibrils in the collected samples.The developed method depends on the trituration under controlled conditions to reduce the fibers to fibrils, separation of the asbestos fibrils from other collected air particulates (beneficiation), and the use of transmission microscopy for identification and quantification. Its validity has been tested by comparative analyses by neutron activation techniques. It can supply the data needed to set emissions criteria and to serve as a basis for assessing the potential hazard for asbestos pollution to the populace.

Asymptomatic Carotid Artery Stenosis

Abstract. Background: After carotid artery stenting (CAS), neurological complications that cannot be explained with imaging methods may develop. In our study we aimed to show, using oxidative stress markers, isolated oxidative damage and resulting neurological findings following CAS in patients with asymptomatic carotid artery stenosis. Patients and methods: We included 131 neurologically asymptomatic patients requiring CAS. The neurological findings were evaluated using the modified Rankin Scale (mRS) prior to the procedure, one hour post-procedure, and two days after. Patients with elevated mRS scores but with or without typical hyperintense lesions observed on an MRI and with changes of oxidative stress marker levels at the time (Δtotal-thiol, Δtotal antioxidative status [TAS], and Δtotal oxidant status [TOS]) were evaluated. Results: In the neurological examination carried out one hour prior to the procedure, there were 92 patients with mRS = 0, 20 with mRS = 1, and 12 with mRS = 2. When Δtotal-thiol, ΔTAS, and ΔTOS values and the mRS were compared, it was observed that as the difference in oxidative parameters increased, clinical deterioration also increased proportionally (p = 0.001). Conclusions: We demonstrate a possible correlation between oxidative damage and neurological findings after CAS which could not be explained by routine imaging methods.
