“…Temperature is a physiological factor affecting fermentation and ATP regulation (Yan et al, 2018). High or low temperatures may impact the biological activity of actinomycetes due to their slow growth (Kanimozhi et al, 2017;Sohn et al, 2023). In turn, this variation modulates the regulatory metabolic pathways and the constitution of the cell wall, resulting in a variety of metabolic responses and the synthesis of a wide array of products (Talukdar et al, 2016).…”

“…To improve the accuracy and safety of brain tumor diagnostic procedures, we plan to combine machine learning, spectroscopy with needle biopsy to guide the selection of the tissue biopsy location (figure 1). Among spectroscopic techniques, Raman spectroscopy is one of the most widely used to analyze materials [7][8][9], and has been applied to detect and classify several types of tumors in open procedures [10,11]. Optical spectroscopy methods, such as Raman and infrared spectroscopy, measure the molecular vibrational states in samples.…”

The traditional definitive diagnosis of brain tumors is performed by needle biopsy under the guidance of imaging-based exams. This paradigm is based on the experience of radiogolists, and accuracy could be affected by uncertainty in imaging interpretation and needle placement. Raman spectroscopy has the potential to improve needle biopsy by providing fingerprints of different materials and performing in situ tissue identification. In this paper, we present the development of a supervised machine learning algorithm using random forest (RF) to distinguish the Raman spectrum of different types of tissue. An integral process from raw data collection and preprocessing to model training and evaluation is presented. To illustrate the feasibility of this approach, viable animal tissues were used, including ectocinerea (grey matter), alba (white matter) and blood vessels. Raman spectra were acquired using a custom-built Raman spectrometer. The hyperparameters of the RF model were determined by combining a cross-validation-based algorithm and manually adjusting. The experimental results show the ability of our approach to discriminate different types of tissues with high accuracy.

“…It is known that the antibacterial activity of ZnO is caused by the production of active oxygen including hydrogen peroxide (H 2 O 2 ), a strong oxidizing agent. 7,8 According to Feris et al, 9 the toxic effects of ZnO nanoparticles on the pathogenic species of bacteria are increased due to the prolonged contact between the bacterium cell membrane and the ZnO nanoparticles. According to the study by Xie et al, 10 the mechanism of ZnO inactivation of bacteria involves direct interaction between the ZnO nanoparticles and cell surfaces.…”

In the present study, the starch films with biosynthesized ZnO nanoparticles were obtained. The films obtained were examined for mechanical properties, environmental toxicity and biodegradation. It was observed that the addition of the ZnO nanoparticles to the polymer matrix caused an increase in the tensile strength and elongation at break. The STEZHP film was characterized by the elongation value at 306 (%). The addition of the nanoparticles had a positive influence on the degradation improvement of the films in question under the three different conditions applied. In turn, the presence of ZnONPs caused an increase in the toxicity of the materials investigated. In the case of the tests for toxicity towards plants, it was observed that the films (SAZ, SAZHP, SAEZ, and STZ) showed very little toxicity, as well as a weak correlation between the parameters of the film quantity and the shoot growth inhibition.
