Summary: In this study, a fast and simple methodology was developed to estimate the total polyphenol content in extra virgin olive oil by combining various spectral data using the multiblock SO-PLS method. The use of different preprocessing algorithms and double cross-validation with 50 iterations improved the robustness of the results. By combining fluorescence and absorbance spectra, the RMSEP median was reduced, while the complexity of the model was decreased, leading to increased robustness. Further validation of the methodology could be achieved by considering a larger sample size and detailed polyphenol composition.

Summary: Sine-square deformation (SSD) is a treatment proposed in quantum systems that gradually decreases the local energy scale from the center of the system towards the edges using a sine-squared envelope function. When applied to classical Ising models, SSD creates an extended canonical ensemble of local subsystems with their own effective temperatures. By normalizing the system temperature by the deformed local energy scale, a single calculation can produce physical quantities at various temperatures that quantitatively reproduce those of the uniform system.

Summary: This study evaluated the effects of temperature, pressure, extraction time, and their interactions on the constituents of essential oil extracted from Piper cor-covadensis using supercritical fluid extraction (SFE). The results showed that pressure and temperature significantly influenced the extraction of constituents, while extraction time was not within the analyzed range. ANOVA-PCA was used to assess the influence of process parameters on each constituent, and the advantages of both ANOVA and univariate ANOVA were compared. Additionally, new constituents were identified during the SFE process.

Summary: The augmented randomized complete block design (ARCBD) is widely used to screen new treatments in plant breeding programs. However, missing control treatment observations can lead to biased estimates. An approximate common approach is to impute the missing values, but this introduces uncertainty. In this paper, an exact scheme and a novel neutrosophic analysis approach are proposed to address the problem of missing control treatments in ARCBD.

Summary: Currently, there are no univariate outlier detection algorithms that can accurately remove univariate outliers from arbitrarily shaped distributions. To address this, we have developed a new algorithm called STAR_outliers, which effectively removes outliers from distributions with various shape profiles. Our results demonstrate that STAR_outliers outperforms other commonly used methods in terms of precision and recall for removing simulated outliers, as well as accurately modeling outlier bounds in real data distributions.

Summary: Neuroinflammation plays a crucial role in both acute and chronic phases of traumatic brain injury (TBI). This study investigated the antioxidant capacity of apple pomace phenolics, phlorizin and phloretin, and their potential use in TBI treatment. The results showed that phloretin exhibited superior antioxidant properties compared to phlorizin, and both compounds regulated common proteins involved in TBI. It was found that estrogen receptor alpha (ESR1) might be a critical cellular hub regulated by both compounds and could be a potential therapeutic target for TBI.

Summary: The research indicates that melatonin can improve lipid metabolism by modifying gut microbiota and glucose metabolism through the melatonin receptor signaling pathway. However, the effect of melatonin consumption on glucose homeostasis by affecting gut microbiota in diabetes has not been studied. In this experiment, melatonin administration through drinking water for 12 weeks in db/db mice, a type 2 diabetes model, showed reduced diabetic symptoms, increased insulin sensitivity, and improved glycemia. Melatonin reprogrammed the gut microbiota and reduced the levels of short-chain fatty acids, leading to enhanced insulin sensitivity and lower fasting blood glucose levels.

Summary: In this study, a Surface-enhanced Raman Spectroscopy (SERS) and chemometric-based metabolomics approach was developed to determine the geographic origins of Keemun black tea. SERS peaks enhanced by Ag nanoparticles were selected and intensities were calculated for chemometric analysis. Linear discriminant analysis (LDA) achieved an average discrimination accuracy of 86.3% and cross-validation of 84.3%, while three machine learning algorithms, feedforward neural network (FNN), random forest (RF), and K-Nearest Neighbor (KNN), achieved recognition rates of 93.5%, 93.5%, and 87.1% respectively. This study demonstrates the potential of using SERS technique coupled with AgNPs and chemometrics as a reliable, fast, and convenient method for determining the geographic origins of teas.

Summary: Bioactive compounds, such as carotenoids, alkaloids, and phenolics, are widely recognized for their health benefits in a balanced diet. They have various bioactivities, including antioxidant, antihypertensive, antihyperglycemic, antilipidemic, anti-obesity, anti-inflammatory, and antimicrobial effects. In vitro methods have been developed to associate the chemical composition of different sources with their bioactivity, but no single test tube-based assay can predict in vivo responses. Therefore, a cell-based method combining in vitro digestion and absorption is proposed to evaluate the antioxidant capacity of compounds, foods, and nutraceuticals.

Summary: This study evaluated the bioactivity and gut microbiota modulation of blackcurrant diets in rats with DMH-induced colon carcinogenesis. The results showed that high doses of blackcurrant increased pro-inflammatory parameters and the expression of anti-apoptotic cytokines, accentuating colon cancer initiation. Additionally, blackcurrant altered the composition and function of the gut microbiome. These findings suggest that high doses of blackcurrant act as a pro-oxidant, exacerbating the inflammatory environment and CRC progression.

Summary: Agrifood system technologies have facilitated the creation of innovative foods with improved nutritional profiles. This article provides an overview of the development of food models/prototypes using natural compounds as a source of inspiration, through the integration of various disciplines and food technologies. To create healthy foods, the combination of interrelated technologies from nutrition, chemical synthesis, pharmacology, and food technology with biological system analyses is proposed. Developing food molecules is a slow process that involves mandatory steps based on desired bioactive properties, which is hindered by the diversity of food matrices and the complexity of reconstituting their biosynthetic pathways. Overcoming these challenges should be a primary focus in food science, leading to more sustainable processes and health benefits.
