    Abstract: A novel intumescent flame retardant system (IFRs) combines Tri (1-oxo-2,6,7-trioxa-1-phosphabicyclo [2. 2. 2] octane-methyl) phosphate (TPMP) with melamine pyrophosphate (MPOP) and its application in polypropylene (PP) has been investigated. The thermal stability, flammability, and water resistance were studied by thermogravimetric analysis (TGA), UL-94 test, and cone calorimetry. TGA shows that pure PP degrades at about 4008C, while sample PP-6 degrades at about 270°C under nitrogen atmosphere. With 30wt% total loading of the IFRs, sample PP-6 passes the UL-94 V-0 test. It can still pass the UL-94 V-0 test after the water treatment. The introduction of TPMP and MPOP strongly decreases the peak heat release rate (PHRR) value of the flame retardant (FR) PP composite. The morphologies of the char residues obtained after cone calorimetry were investigated by means of scanning electron microscopy (SEM). The char residue of sample PP-6 has better structure, which prevents the underlying materials from further decomposing. X-ray photoelectron spectroscopy (XPS) was used to further explore the char residues of the FR PP composites. The results show that sample PP-6 has the best char residue, which enhances the oxidation resistance of the char layer.

    Recovery of Variable Loadings and Eigenvalues Directly from Fourier Compressed Ion Mobility Spectra
    SAGE Publications ; 1998
    In:  Applied Spectroscopy Vol. 52, No. 10 ( 1998-10), p. 1328-1338
    Details
    In: Applied Spectroscopy, SAGE Publications, Vol. 52, No. 10 ( 1998-10), p. 1328-1338
    Abstract: A discrete sine transform (DST) method has been devised for the Fourier compression of ion mobility spectra. The DST allows the calculation of eigenvalues with correct scale directly from the compressed data. A novel procedure for transforming the variable loadings from Fourier to native domains has been devised. For the first time, data may be interpreted in their native domain without decompression of the entire data set. This achievement is significant because results generated from the analysis of compressed data had been restricted to an abstract mathematical form. Methodology to convert these abstract results to a form that is understandable by analytical chemists is presented. This capability has important applications to the analysis of large data sets and embedded data processing under the constraints of miniaturized instrumentation. Five sets of evaluation data were obtained from vapor samples of formamide, 1-pentanol, and a mixture of two chemical warfare simulants (DIMP and DMMP) with a handheld ion mobility spectrometer (IMS). These data sets were compressed by 90% or more and reconstructed with 1% or less relative error. IMS instruments can generate thousands of spectra per hour. MATLAB functions for the DST, the inverse DST, and the two-dimensional DST are furnished in the Appendix.

    Abstract: Ion mobility spectrometry (IMS) has been successfully developed to yield an advanced portable instrument. However, the formation of pure or heterogeneous cluster ions introduces nonlinear variances into the data. Cluster ions may arise from the sample in addition, and competition to the standard anticipated product ions and may deleteriously affect quantitative determinations. The SIMPLISMA (simple-to-use interactive self-modeling mixture analysis) method is demonstrated for detecting and modeling these nonlinear variances in IMS data, which is especially useful when vapor mixtures are encountered. Furthermore, SIMPLISMA may assist in the resolution of overlapping peaks that are characteristic of low-resolution IMS drift tubes. The synergistic combination of IMS and SIMPLISMA is shown for the detection of heterogeneous cluster ions produced from vapor mixtures of 1-pentanol and 1-octanol.

    Abstract: Children younger than three years old are able to detect hidden rules in numerical sequences, and this ability matches that of adults by age seven. However, the developmental trajectory of this ability during the ages of four to six remains unknown. The present study adopted a modified Brixton task to address this issue. In this task, children were presented with sequences of moving circles and were asked to predict which circle would next turn blue based on hidden rules that were either simple (e.g. + 2) or complex (e.g. + 2 – 1). Results suggested that (a) four-year-olds were only able to detect comparably few simple rules, whereas children older than 4.5 years were able to successfully detect most of the simple rules hidden in number sequences; (b) although all children performed significantly poorer when attempting to identify complex rules as compared with simple rules, rule detection (RD) ability improved rapidly with age, and children older than five were able to identify most complex rules. These findings extended previous work on rule learning by revealing the developmental trajectory of RD among preschoolers.

    Abstract: To investigate factors associated with fetal fraction and to develop a new predictive method for low fetal fraction before noninvasive prenatal testing. Methods: The study was a retrospective cohort analysis based on the results of noninvasive prenatal testing, complete blood count, thyroxin test, and Down's syndrome screening during the first or second trimester in 14,043 pregnant women. Random forests algorithm was applied to predict the low fetal fraction status (fetal fraction 〈 4%) through individual information and laboratory records. The performance of the model was evaluated and compared to predictions using maternal weight. Results: Of 14,043 cases, maternal weight, red blood cell, hemoglobin, and free T3 were significantly negatively correlated with fetal fraction while gestation age, free T4, pregnancy-associated plasma protein-A, alpha-fetoprotein, unconjugated estriol, and β-human chorionic gonadotropin were significantly positively correlated with fetal fraction. Compared to predictions using maternal weight as an isolated parameter, the model had a higher area under the curve of receiver operating characteristic and overall accuracy. Conclusions: The comprehensive predictive method based on combined multiple factors was more effective than a single-factor model in low fetal fraction status prediction. This method can provide more pretest quality control for noninvasive prenatal testing.

    Abstract: The differential diagnosis of pleural effusion is difficult, and studies have reported on the potential role of adenosine deaminase (ADA) in the differential diagnosis of undiagnosed pleural effusion. This retrospective study aimed to investigate the diagnostic role of ADA in pleural effusion. Methods: 266 patients with pleural effusion from three centers were enrolled. The concentrations of ADA and lactate dehydrogenase (LDH) were measured in pleural fluids and serum samples of the patients. The diagnostic performance of ADA-based measurement for tuberculous pleural effusion (TPE), malignant pleural effusion (MPE), and parapneumonic effusion (PPE) was examined by receiver operating characteristic (ROC) curve analysis. Results: An area under the ROC curve (AUC) value of 0.909 was obtained using the pleural ADA values as the indicator for TPE identification (sensitivity: 87.50%, specificity: 87.82%). The ratio of serum LDH to pleural ADA (cancer ratio) provided the predictive capacity with an AUC of 0.879 for MPE diagnosis (sensitivity: 95.04%, specificity: 67.06%). At a cut-off value of 14.29, the pleural ADA/LDH ratio showed a sensitivity and specificity of 81.13% and 83.67%, respectively, and a high AUC value of 0.888 for the differential diagnosis of PPE from TPE. Conclusion: ADA-based measurement is helpful for the differential diagnosis of pleural effusion. Further studies should be performed to validate these results.

    Abstract: T cell immunoglobulin and mucin domain 3 (TIM3) expression is associated with immunosuppression and clinical outcomes in many diseases. However, the specific mechanism of TIM3 in immune system has not been clarified. In order to illustrate the mechanism of TIM3 in immune system, we analyzed the expression, function and regulation of TIM3 in T helper (Th)1 cells, Th2 cells, Th17 cells and regulatory T cells (Treg) through flow cytometry in patients with myelodysplastic syndrom (MDS). Our data showed elevated proportion of Th2 and Treg cells, while the proportion of Th1 and Th17 cells decreased in patients with MDS (p 〈 0.05) and the expression of TIM3 increased in Th1, Th17 and Treg cells in patients with MDS when compared with expression in control patients (p 〈 0.05). The secretion of transforming growth factor-β in TIM3+Treg cells decreased in patients with MDS. These findings suggested that TIM3 might affect immune helper systems by regulating Treg cells and related immune cells. Therefore, studying the role of the TIM3 pathway in MDS is necessary and may help to provide a new way to explore the pathogenesis and treatments of MDS.

    In: Clinical and Applied Thrombosis/Hemostasis, SAGE Publications, Vol. 28 ( 2022-01), p. 107602962211126-
    Abstract: To investigate the significance of thrombelastography (TEG) in patients who have lung adenocarcinoma in situ (LAIS) complicated with type 2 diabetes (T2D), 120 subjects were enrolled: 40 with LAIS, 40 with LAIS and T2D (LAIS + T2D), and 40 healthy controls (HCs). Correlation analysis was used to assess the relationships of TEG with indicators of T2D. The LAIS + T2D group had lower reaction time (R), rate of clot formation (K), estimated percentage of lysis (EPL), and lysis after 30 min (LY30), but higher maximum amplitude (MA), angle (α), and coagulation index (CI) than other group. Compared with the HC group, the LAIS group had lower R, K, EPL, and LY30, but higher MA, α, and CI. In LAIS + T2D group, R and LY30 had negatively correlations with fasting blood glucose (FBG) and triglycerides (TGs); α and MA had positive correlations with FBG and TG; K had negative correlations with FBG; EPL had negative correlations with FBG and low-density lipoprotein (LDL); and CI had positive correlations with FBG and LDL. TEG may be a useful indicator of blood coagulation dysfunction in these patients rather the healthy individuals.
