Summary: FTIR-PAS was used for quick assessment of rice quality in response to rising CO2/temperature, with PCA identifying the influences of elevated CO2 and higher temperature. Intensities of selected spectral bands showed positive linear correlation with starch, protein, and lipid content, demonstrating the potential of FTIR-PAS to detect rice responses to climate change.

Summary: Fourier transform infrared (FTIR) spectroscopy is a vibration spectroscopy that uses infrared radiation to absorb the molecular bonds in its absorbed sample. The study aimed to evaluate FTIR spectroscopy as a diagnostic tool for lymph node metastasis (LNM) of gastric cancer. Spectral analysis was conducted on 160 fresh lymph nodes from patients with gastric cancer using FTIR. The results showed that FTIR spectroscopy has high sensitivity and specificity in diagnosing LNM, making it a potential non-invasive method for clinical practice.

Summary: This study compared the drying characteristics and quality attributes of okra dried using different techniques, including sun drying, an evacuated tube solar dryer with heat pipe (ETSD_HP), and an evacuated tube solar dryer without heat pipe (ETSD_WHP). The results showed that the sample pre-treated at 80 degrees C and dried in ETSD_HP had the highest moisture diffusivity. The bioactive compounds and functional properties of okra were better retained in both ETSD_HP and ETSD_WHP techniques compared to sun drying. ETSD_HP was recommended for its increased moisture diffusion and maximum retention of bioactive compounds.

Summary: Vibrational analysis is a powerful tool for unraveling differences during malignant transformation, but data interpretation can be complicated due to the large amount of information generated by all chemical bonds in the sample. In this study, attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy and principal component analysis (PCA) were used to differentiate primary fibroblasts from cervical cancer cell lines. The results demonstrate the sensitivity of vibrational analysis in proposing new methods for disease detection.

Summary: An in-depth understanding of the bonding mechanism of botanical concrete (BC) is crucial for improving its performance and development. The study found that the alkalinity and temperature have significant effects on the bonding of BC, with alkalinity playing a more important role. Combining BC with alkaline industrial wastes or novel geopolymers can enhance its applicability.

Summary: Real-time monitoring of the thermooxidative degradation behavior of ABS was achieved using isothermal in-situ FTIR measurements combined with PCA. By applying PCA to the time-dependent spectral data obtained during the aging process, crucial information was effectively extracted to draw meaningful conclusions. The in-situ characterization revealed the aging behavior of ABS at different temperatures, including oxidation, chain scission, volatilization of polybutadiene, and consumption of the flame retardant. The technique provides a better understanding of the thermooxidative degradation mechanisms of polymers.

Summary: The accurate post-mortem diagnosis of the pathological degree of myocardial infarction (MI) is crucial in clinical and forensic investigations. Fourier transform infrared (FTIR) microspectroscopy, combined with intelligent algorithms, has shown potential for identifying pathological phases in human infarcted cardiac tissues. The results of this study demonstrate the feasibility of using FTIR microspectroscopy for evaluating the pathological degree of MI post-mortem.

Summary: Obesity is a significant risk factor for obesity-associated diseases globally. This study proposes two spectral regions, 800-1800 cm(-1) and 2700-3000 cm(-1), as potential biomarkers for obesity-related biochemical changes using Fourier transform infrared (FT-IR) analysis. By evaluating biochemical characteristics and clinical parameters, the study successfully distinguished obese and control groups and suggests FTIR analysis as a reliable method for blood serum analysis in obese patients.

Summary: High humidity hot air impingement blanching (HHAIB) affects the physicochemical properties of polysaccharides and phytochemicals in okra pods. The pectin fractions consisted of various components including polygalacturonic acid, rhamnogalacturonan, glucomannan, galactan, mannose, arabinose, rhamnose, calcium pectate, and arabinogalactan. HHAIB increased the contents of total phenolics, total flavonoids, and antioxidant activity, but decreased the chlorophyll-a and lycopene contents in okra pods.

Summary: The study utilized Fourier transform infrared microspectroscopy and Raman microscopy to investigate local and remote biochemical changes in the rat brain, revealing significant biomolecular anomalies within the lesion site but not in the area of the dorsal hippocampal formation and in the above situated white matter and cortex. The observed intralesional anomalies included decreased accumulation of lipids and levels of compounds containing phosphate and carbonyl groups, while an opposite relationship was found for proteins and cholesterol/cholesterol esters.

Summary: Researchers have developed a method called orthogonal smoothed PCA for statistical hypothesis testing of metabolomics data to select significant metabolites. This method was successfully applied to two real datasets with promising results, indicating that OS-PCA combined with statistical hypothesis testing is a useful approach for metabolome data analysis.
