The affected extremities and corresponding implantation sites were examined using computer tomographic scans (CT), additional CT angiography (CTA), reconstruction techniques and postprocessing procedures.
It was possible to prove a close relation between the implanted device and the neurovascular bundle in each of these cases. Thus, indirect lead position control was obtained.
Computer tomographic techniques represent a reliable method for the position control of implanted peripheral nerve electrodes. Hence, this procedure
should surpass general radiographies in detecting lead displacements.”
“Sleep and headache are linked in a bidirectional way. Breathing quality during sleep may be a possible link between them. The objective of Bucladesine nmr this study were to evaluate the prevalence of headache-and of allodynia-in a population of subjects who
underwent cardiopulmonary monitoring during sleep for presumed respiratory problems; to evaluate the possible relationships between the presence of headaches-and of allodynia-and respiratory parameters. We studied 181 subjects, 112 without headache (mean age 59.4 +/- A 13.1 years, 97 men and 15 women); 69 with history of headache (42 men and 27 women; 41 migraineurs and 28 with tension type headache). Headache diagnosis was made according to ICHD-II criteria. A semi-structured ad hoc questionnaire LY3023414 nmr was used to evaluate the presence of allodynia. Full cardiopulmonary monitoring was performed by SOMNO check(A (R)) effort (WEINMANN) with SaO(2), T90 and AHI determination. Headache and headache-associated allodynia were particularly frequent in this population, suggesting a positive selleck inhibitor correlation between
breathing problems during sleep and head pain, and allodynia. The observation that better respiratory parameters were found among headache sufferers with respect to those without headache, even in allodynic subjects, seems to reverse this point of view: headache and allodynia may possibly have an allostatic function preventing deep sleep and, in turn, avoiding prolonged apneas.”
“Poly(p-phenylene benzobisoxazole)/multiwalled carbon nanotubes (PBO-MWCNT) composites with different MWCNT compositions were prepared through in situ polymerization of PBO in the presence of carboxylated MWCNTs. The nanocomposite’s structure, thermal and photophysical properties were investigated and compared with their blend counterparts (PBO/MWCNT) using Fourier transform infrared spectra, Raman spectra, Wide-angle X-ray diffraction, thermogravimetric analysis, UV-vis absorption, and photoluminescence. The results showed that MWCNTs had a strong interaction with PBO through covalent bonding. The incorporation of MWCNTs increased the distance between two neighboring PBO chains and also improved the thermal resistance of PBO.
