Non-destructive characterisation and classification of ceramic artefacts using pEDXRF and statistical pattern recognition
Springer Science and Business Media LLC - Tập 6 - Trang 1-9 - 2012
Maja D Gajić-Kvaščev, Milica D Marić-Stojanović, Radmila M Jančić-Heinemann, Goran S Kvaščev, Velibor Dj Andrić
Portable energy dispersive X-ray fluorescence (pEDXRF) spectrometry analysis was applied for the characterisation of archaeological ceramic findings from three Neolithic sites in Serbia. Two dimension reduction techniques, principal component analysis (PCA) and scattering matrices-based dimension reduction were used to examine the possible classification of those findings, and to extract the most ...... hiện toàn bộ

QSAR study on the removal efficiency of organic pollutants in supercritical water based on degradation temperature
Springer Science and Business Media LLC - Tập 12 - Trang 1-8 - 2018
Ai Jiang, Zhiwen Cheng, Zhemin Shen, Weimin Guo
This paper aims to study temperature-dependent quantitative structure activity relationship (QSAR) models of supercritical water oxidation (SCWO) process which were developed based on Arrhenius equation between oxidation reaction rate and temperature. Through exploring SCWO process, each kinetic rate constant was studied for 21 organic substances, including azo dyes, heterocyclic compounds and ion...... hiện toàn bộ
Using crystallography, topology and graph set analysis for the description of the hydrogen bond network of triamterene: a rational approach to solid form selection
Springer Science and Business Media LLC - Tập 11 - Trang 1-19 - 2017
David S. Hughes, Amit Delori, Abida Rehman, William Jones
This study has demonstrated the use of crystallography, topology and graph set analysis in the description and classification of the complex hydrogen bonded network of triamterene. The aim is to give a brief overview of the methodology used to discuss the crystal structure of triamterene with a view to extending the study to include the solvates, cocrystals and salts of this compound. ...... hiện toàn bộ
Tissue-specific metabolite profiling and quantitative analysis of ginsenosides in Panax quinquefolium using laser microdissection and liquid chromatography–quadrupole/time of flight-mass spectrometry

The octanol/water distribution coefficients of ardipusilloside-I and its metabolites, and their permeation characteristics across Caco-2 cell monolayer
Springer Science and Business Media LLC - Tập 10 - Trang 1-8 - 2016
Wei-yu Cao, Bin Feng, Li-fei Cheng, Ying Wang, Ji Wang, Xiao-juan Wang
Ardipusilloside-I (ADS-I) is a triterpenoid saponin extracted from Chinese medicinal herb Ardisiapusill A. DC. Previous studies have demonstrated the potent anti-tumor activities of ADS-I both in vitro and in vivo, and its main metabolites (M1 and M2) from human intestinal bacteria. However, the physicochemical properties and intestinal permeation rate of ADS-I and its metabolites are not understo...... hiện toàn bộ

Effective separation and simultaneous analysis of anabolic androgenic steroids (AAS) in their pharmaceutical formulations by a validated TLC-densitometry method
Springer Science and Business Media LLC - Tập 6 - Trang 1-7 - 2012
Syed Ghulam Musharraf, Umair Gulzar
Anabolic androgenic steroids (AAS) are widely misused for the enhancement of performance in sports. Several drugs are available that contain different combinations or individual steroids in different dosage form. This paper describes a TLC densitometric method for simultaneous determination of four AAS of testosterone derivatives including testosterone propionate (TP), testosterone phenyl propiona...... hiện toàn bộ
Finding one's way in proteomics: a protein species nomenclature
Springer Science and Business Media LLC - Tập 3 - Trang 1-10 - 2009
Hartmut Schlüter, Rolf Apweiler, Hermann-Georg Holzhütter, Peter R Jungblut
Our knowledge of proteins has greatly improved in recent years, driven by new technologies in the fields of molecular biology and proteome research. It has become clear that from a single gene not only one single gene product but many different ones - termed protein species - are generated, all of which may be associated with different functions. Nonetheless, an unambiguous nomenclature for descri...... hiện toàn bộ
