1Impact of corneal parameters on intraocular pressure measurements in different tonometry methods显示文摘AIM: To evaluate the impact of central corneal thickness(CCT) and corneal curvature on intraocular pressure(IOP) measurements performed by three different tonometers. METHODS: IOP in 132 healthy eyes of 66 participants was measured using three different tonometry techniques: Goldmann applanation tonometer(GAT), Pascal dynamic contour tonometer(DCT), and ICare rebound tonometer(RT). CCT and corneal curvature were assessed. RESULTS: In healthy eyes, DCT presents significantly higher values of IOP than GAT(17.34±3.69 and 15.27±4.06 mm Hg, P<0.0001). RT measurements are significantly lower than GAT(13.56±4.33 mm Hg, P<0.0001). Compared with GAT, DCT presented on average 2.51 mm Hg higher values in eyes with CCT<600 μm and 0.99 mm Hg higher results in eyes with CCT≥600 μm. The RT results were lower on average by 1.61 and 1.95 mm Hg than those obtained by GAT, respectively. Positive correlations between CCT in eyes with CCT<600 μm were detected for all IOP measurement techniques, whereas a similar relationship was not observed in eyes with thicker corneas. A correlation between IOP values and keratometry in the group with CCT<600 μm was not detected with any of the tonometry methods. In thicker corneas, a positive correlation was found for GAT and mean keratometry values(R=0.369, P=0.005). CONCLUSION: The same method should always be chosen for routine IOP control, and measurements obtained by different methods cannot be compared. All analysed tonometry methods are dependent on CCT;thus, CCT should be taken into consideration for both diagnostics and monitoring.Aleksandra Zakrzewska Marta P.Wi?cek Anna Machalińska 2019International Journal of Ophthalmology(English edition)2019,12,12:5
2Biochar surface functional groups as affected by biomass feedstock, biochar composition and pyrolysis temperature显示文摘By testing 92 different biochars,this study had the objective to determine the relations between simple physico-chemical characteristics of biochar(elemental composition,ash fraction,specific surface area,process parameters)and infrared sorption characteristics revealing the presence of specific functional groups.The results of Diffusive Reflection Fourier Transformation Infrared Spectroscopy were statistically analyzed with multiple linear regression techniques and Principal Component Analysis(PCA)with the biochar characterization parameters as model inputs.The dominant parameters affecting the functional group signals were the pyrolysis temperature,the H/C-ratio and specific surface area of the biochar and the ash fraction.Regression models were able to explain 60-90%of data variance for specific peaks in the DRIFTS-spectra.The application of PCA could further reduce the input parameters to three main factors explaining 70.8%of total data variance.Biplots of the first two main factors showed the similarity of infrared spectra of biochars produced at 300 and 450℃,whereas a pyrolysis temperature of 600℃ lead to a partial and a 750℃ to a nearly complete loss of biochar surface functional groups.Rainer Janu Verena Mrlik Doris Ribitsch Jakub Hofman Petr Sedlácek Lucie Bielsk Gerhard Soja 2021Carbon Resources Conversion2021,4,1:5
3适用于糖尿病患者皮鞋鞋材的抗菌防霉复配剂的筛选显示文摘利用具有不同抗菌机理的五种抗菌防霉剂,即4-(2-苯并噻唑基亚氨甲基)苯氧乙酸锌(A)、尼泊金丁酯(B)、山梨酸(C)、百菌清(D)、异噻唑啉酮(E)之间的协同和加合作用,成功开发出了用于糖尿病患者皮鞋鞋材的复配型抗菌防霉剂。首先,以糖尿病患者鞋内分离出来的代表性细菌、酵母菌和霉菌为供试菌种,采用滤纸条交叉放药法对五种抗菌组分进行了复配,结果表明,去除对菌种有拮抗作用的复配组分,有效的复配组分为:A和B、A和E、B和C、B和E、C和E。然后,以等浓度的混合菌为供试菌种,对各种有效组分进行不同比例的复配,并测定了复配后的抑菌圈直径,结果显示,优化复配比例为:A∶B=3∶7、2∶8、1∶9;A∶E=6∶4、4∶6、2∶8;B∶E=5∶5、2∶8;C∶E=3∶7、2∶8。用这些优化复配组分可以有效的抵御糖尿病患者鞋内的病原微生物,这就为它们在糖尿病患者鞋材上的应用提供了参考。赵长青 辜海彬 Petr Hlavácek 陈武勇 2008皮革科学与工程2008,18,1:2
