The role of human cytomegalovirus (HCMV) in lung transplantation (LT) and drawbacks related to viral quantification in bronchoalveolar lavage (BAL) underline the potential usefulness of investigating other specimens. Thirty-three LT recipients were prospectively studied by HCMV quantitative real time PCR on matched transbronchial biopsy (TBB), BAL, and whole blood specimens. Overall, 27/33 patients turned out HCMV-positive in at least one specimen: 7.1 %, 37.1 %, and 13.5 % of TBB, BAL, and blood samples, respectively. No significant association between HCMV on all types of specimens and acute rejection, lymphocytic bronchiolitis, bronchiolitis obliterans and bronchiolitis obliterans syndrome was found. HCMV pneumonia was associated to HCMV detection on TBB (p = 0.003) and whole blood (p = 0.008), not on BAL (p = 0.47). The highest mean viral load was detected in TBB from cases with HCMV pneumonia in comparison to all other cases, suggesting the potential use of HCMV investigation in TBB for evaluating posttransplant complications. 相似文献

IntroductionThe aim of this study was to investigate the influence of mass and the polar moment of inertia on the torsional behavior of nickel-titanium rotary instruments to understand which parameter of cross-sectional design had a key role in terms of torsional resistance.MethodsFour different instrument models were designed and meshed using computer-aided engineering software (SolidWorks; Dassault Systems, Waltham, MA). Instrument models shared the same characteristics, except for cross-sectional design; triangle, rectangle, square, and hollow square geometry was selected. Finite element analysis was performed simulating a static torsional test using the FEEPlus internal solver (Solid Works). Von Mises stress and torsional load at fracture were calculated by the software. Linear regression analysis was performed to investigate the relationship of the polar moment of inertia, cross-sectional area, inner core radius, and mass per volume on the torsional resistance of nickel-titanium rotary instruments.ResultsThe polar moment of inertia positively affected the maximum torsional load with the highest level of correlation (R2 = 0.917). It could be stated that the higher the polar moment of inertia is, the more maximum torsional load at fracture is present. Mass and cross-sectional area had a lower level of correlation compared with the polar moment of inertia (R2 = 0.5533). According to this, 2 instruments with the same mass/mm and/or cross-sectional area could have different torsional resistance.ConclusionsThe polar moment of inertia can be considered as the most important cross-sectional factor in determining the torsional resistance of rotary instruments over metal mass and cross-sectional area. 相似文献

The two essential requirements for pathologic specimens in the era of personalized therapies for non-small cell lung carcinoma (NSCLC) are accurate subtyping as adenocarcinoma (ADC) versus squamous cell carcinoma (SqCC) and suitability for EGFR molecular testing, as well as for testing of other oncogenes such as EML4-ALK and KRAS. Actually, the value of EGFR expressed in patients with NSCLC in predicting a benefit in terms of survival from treatment with an epidermal growth factor receptor targeted therapy is still in debate, while there is a convincing evidence on the predictive role of the EGFR mutational status with regard to the response to tyrosine kinase inhibitors (TKIs).This is a literature overview on the state-of-the-art of EGFR oncogenic mutation in NSCLC. It is designed to highlight the preclinical rationale driving the molecular footprint assessment, the progressive development of a specific pharmacological treatment and the best method to identify those NSCLC who would most likely benefit from treatment with EGFR-targeted therapy. This is supported by the belief that a rationale for the prioritization of specific regimens based on patient-tailored therapy could be closer than commonly expected. 相似文献
