“…On a particular PC, if the score of a sample and the loading of a variable (wavelength/wavenumber) have the same sign, this refers that the sample has higher than the average value for that variable and vice-versa. The larger the scores and loadings, the stronger that relation (Martin et al 2014). For the analyzed samples, loadings plot revealed 7 positive discriminators detected approximately at 1110 cm -1 , 1080 cm -1 , 1047 cm -1 , 1032 cm -1 , 995 cm -1 , 980 cm -1 , and 960 cm -1 along PC-1 (Figure 2B).…”

Probiotics play important roles in many crucial functions for maintaining the homeostasis of the host, such as protection against pathogens, immunity and metabolism of dietary compounds. Resistant starch (RS) is the starch or the starch products which cannot be digested through the body, but can be digested by the gut microbiota, producing a variety of metabolites which can provide a range of physiological benefits to the host. An RS can be classified as a prebiotic if it can selectively stimulate the growth and/or activity of the beneficial bacteria. To investigate the bacteria driven structural changes in the prebiotic tapioca starch, we used Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy. Principal Component Analysis (PCA) and intensity analyses of individual spectral bands exhibited comprehensive alterations in the polysaccharide composition of the tapioca starch incubated with the probiotic bacteria; the starch samples incubated with the bacteria gained a more amorphous structure with a decrease in the ordered structure. The results suggest that as a fast, cheap, and non-laborious method, FTIR spectroscopy coupled with PCA has a potential to be applied in the research area as well as in the food industry for the analysis of the potential prebiotic activity of starch-based substrates or the investigation of the probiotic potential of a bacterial strain through the examination of its RS hydrolyzing capacity.

“…The integrity of the specimen can be compromised before it is analyzed, by contamination during collection and processing or by the attenuation of the analytic concentration during storage. If this happens, the determined values are not valid even though the method of analysis is extremely sensitive and highly accurate [3].…”

Breast cancer, or malignant breast neoplasm, is a type of cancer that originates from breast tissue, most commonly from the inner lining of the milk ducts or the lobules that supply the ducts with milk. It is one of the most widespread diseases, especially in women. Thus far, large efforts have been towards the early diagnosis of cancer in general, and breast cancer specifically. Most of these techniques deal with malignant tissues without inducing or increasing pathological tissue changes or causing major side effects for the patient. This paper proposes a new technique for diagnosing the presence or occurrence of cancer and assessing its grade early, accurately, and safely. The presented technique depends on the interaction between the laser and the soft tissue in order to induce plasma, and allows us to classify the cancer by studying the difference in the intensity ratio of the trace elements in normal and malignant tissues. The results presented here are show that only four patients out of the total sample of 30 have erroneous trace elements and that this does not affect the overall decision. Hence, the performance of LIPS can be measured as 87%, while retaining 100% accuracy. Furthermore, LIPS technique is a simple and promising technique that is capable of diagnosing malignant cells and tissues

Review of Element Analysis of Industrial Materials by In-Line Laser—Induced Breakdown Spectroscopy (LIBS)

Laser-induced breakdown spectroscopy (LIBS) is a rapidly developing technique for chemical materials analysis. LIBS is applied for fundamental investigations, e.g., the laser plasma matter interaction, for element, molecule, and isotope analysis, and for various technical applications, e.g., minimal destructive materials inspection, the monitoring of production processes, and remote analysis of materials in hostile environment. In this review, we focus on the element analysis of industrial materials and the in-line chemical sensing in industrial production. After a brief introduction we discuss the optical emission of chemical elements in laser-induced plasma and the capability of LIBS for multi-element detection. An overview of the various classes of industrial materials analyzed by LIBS is given. This includes so-called Technology materials that are essential for the functionality of modern high-tech devices (smartphones, computers, cars, etc.). The LIBS technique enables unique applications for rapid element analysis under harsh conditions where other techniques are not available. We present several examples of LIBS-based sensors that are applied in-line and at-line of industrial production processes.
