To determine whether Fourier transform (FT)-IR spectral analysis combined with multivariate analysis of whole-cell extracts from ginseng leaves can be applied as a high-throughput discrimination system of cultivation ages and cultivars, a total of total 480 leaf samples belonging to 12 categories corresponding to four different cultivars (Yunpung, Kumpung, Chunpung, and an open-pollinated varie...

An impressive collection of chert artefacts from the Foeni Neolithic archaeological site (Timiş County, Banat region, Romania) is hosted by the Banat Museum in Timişoara. A representative set of seven specimens was non-destructively investigated using FT-Raman and ATR-FT-IR spectroscopy. The research was carried out for checking if these readily available, non-destructive, fast, and cheap metho...

A collection of bacteria belonging to the genus Bacillus were analysed by diffuse reflectance absorbance and attenuated total reflectance Fourier transform infrared (FT-IR) spectroscopy in the mid-infrared. The diffuse reflectance absorbance method is a rapid whole organism fingerprinting method, which generates a biochemical profile of the bacteria, where samples are presented to the FT-IR spe...

OBJECTIVES This work deals with the conformational and thermal characterization of a synthetic peptide (S4) released during the proteolysis of human tropoelastin by the matrix metalloproteinase-12 that was shown to form amyloid-like fibres under certain conditions. MATERIALS AND METHODS S4 peptides were synthesized by solid-phase methodology and aggregated in solution at 80°C. Fourier transfo...

The aim of the present study was to investigate the possibility of using infrared spectroscopy for detecting the irradiation of meats. Samples of beef meat containing fat were subjected to gamma irradiation at doses of 0, 1.5, 3 and 4.5 kGy at room temperature. Then irradiated and non-irradiated beef meat samples were examined by Fouriertransform infrared (FT-IR) spectroscopy post irradiation t...

Fourier transform infrared (FT-IR) spectroscopy combined with multivariate statistical analyses was investigated as a physicochemical tool for monitoring secreted recombinant antibody production in cultures of Chinese hamster ovary (CHO) and murine myeloma non-secreting 0 (NS0) cell lines. Medium samples were taken during culture of CHO and NS0 cells lines, which included both antibody-producin...

Purpose To compare the results of a chemical method of kidney stone analysis with the results of Fourier transform infrared (FT-IR) spectroscopy. Materials and Methods Kidney stones collected between June and October 2015 were simultaneously analyzed by chemical and FT-IR methods. Results Kidney stones (n=449) were collected from patients from 1 to 81 years old. Most stones were from adults...
