TurkyAbstractTextile fabrics possess multitude applications and a wide variety of highly technical uses. Microfiber is one of the most popular synthetic fibers. Its popularity is a result of special properties such as good resiliency, heat resistance, light weight, water proof and durability. In the present work, two woven fabrics were synthesized from polyester microfiber and then coated by calcium silicate/copper oxide-nanoparticles, (CaO3Si/CuO)-NPs, using low temperature plasma (dielectric barrier discharge) technique. The coated textiles were investigated by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX). A broadband dielectric spectroscopy (BDS) was employed to study the treatment conditions on the electrical and dielectric properties over a wide range of frequencies. The results showed that, the resistivity of the textile samples was remarkably enhanced upon coating with the (CaO3Si/CuO)-NPs) accompanied by a reduction of the static charges accumulated on the surface. These results made the plasma sprayed coated textiles promising for electrical applications like cables isolation as well as packing and packaging.
This study compares the effect of Helicobacter (H.) pylori and Lactobacillus (L.) acidophilus on the cytokine profile of PBMCs of 5 men with abdominal aortic aneurysm (AAA) and 5 men with normal/insignificant angiography, CT-Scan and ultrasonography results in the single-culture and in the co-culture with HUVECs. IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-17A, IL-17 F, IL-21, IL-22, IFN-γ and TNF-α were measured in culture supernatants using a commercial fluorescent-labeled-bead assay.In general, CagA+ H. pylori-extract induced higher production of IFN-γ, IL-13 and IL-21 by PBMCs. Treatment of ...

VincentAbstractImmunofluorescence on cleared intact cochlea allows detailed analysis of the cochlear ultrastructure, while avoiding the problems of dissection and serial sections. Protocols have been developed for mice and Mongolian gerbils. This technical note proposes a detailed and optimised immunofluorescence protocol in the Mongolian gerbil comprising significant quantitative and qualitative improvements. This protocol sequentially co...
CONCLUSION: The use of RGP prior to ureteral stent placement for an obstructing ureteral stone with concomitant UTI was not associated with unfavorable clinical outcomes in our retrospective series. While these findings support the safety of RGP in this setting, prospective trials are warranted. PMID: 32065871 [PubMed - in process]
CONCLUSION: Long-term survival following EPS managed conservatively with nutritional support is feasible, with the majority no longer requiring nutritional support and having a quality of life similar to other patients with ESKD. PMID: 32067553 [PubMed - as supplied by publisher]
This article describes a method of integrating digital dental casts into cone beam computed tomography (CBCT) scans in virtual implant planning in situations with an excessive number of metal artifacts. This technique requires the use of a prefabricated registration tray to provide a common landmark; is noninvasive, minimally time-consuming, and cost-effective; and requires only a single registration and minimal exposure to radiation.

Thompson, Carl Drago, Fahimeh Tabatabaei, Morteza RasoulianboroujeniAbstractStatement of problemSoft-tissue attachment to different surfaces may play a pivotal role in the long-term success of dental implants. However, studies on the issue, especially on newer materials, are sparse.PurposeThe purpose of this in vitro study was to evaluate the viability and adhesion of human gingival fibroblasts (HGFs) on different implant abutment materials with specific surface modifications.Materia...
Conclusion Conventional CT and FDG PET parameters are not adequately specific for determination of a benign lesion in this selected cohort of high-risk patients. Use of 131I-norcholesterol in this patient cohort may provide additional value.
Conclusion RIT in postthyroidectomy setting can be successfully performed within 90 days after CCT. Further research is needed to confirm our findings.
Conclusion Robotic-assisted CT-guided 18F-FDG PET/CT-directed biopsy is a useful and accurate technique for diagnostic evaluation of intrathoracic neoplasms with minimal complications rates as compared with conventional imaging techniques.
Conclusion 18F-FDG PET/CT seemed to be an excellent diagnostic test in assessment of BMI at initial assessment and staging of Hodgkin lymphoma and DLBCL patients.
