Summary: Plants produce a wide variety of sterols through complex biosynthetic pathways, which play crucial roles in plant growth hormones and signal transduction. While some enzymatic steps are evolutionarily conserved, there are also entirely different enzymes involved in the biosynthetic pathways, which has important implications for the use of plant-specific sterol biosynthesis inhibitors.

Summary: This study revealed that the sterol levels in CF patients were influenced by factors such as genotype, pancreatic insufficiency, pancreatic enzyme dose, and nutritional status. Malabsorption and pancreatic enzyme supplementation played a significant role in sterol abnormalities in CF patients.

Summary: It was found that brassicasterol-d(1) exists in the serum of stroke-prone spontaneously hypertensive rats. Therefore, an analytical method was developed to simultaneously determine the serum concentration of ergosterol-d(1) and brassicasterol-d(1). The experimental results showed that the peak serum concentration of brassicasterol-d(1) was 3 times higher than that of ergosterol-d(1).

Summary: Phytosterols are important components of plant cells and have effects on membrane properties and metabolic regulation. A study on four major corn cultivars in South Korea found that phytosterol levels in corn cobs were twice as high as those in kernels, with the highest levels observed in Sinhwangok kernels and cobs after 60 days of pollination.

Summary: Sterols can be concatenated or undergo oxidation reactions under high-temperature treatment. This study aimed to prove the existence of oxidized 3 beta,3 'beta-disteryl ethers that may form during high-temperature treatment of sterol-rich samples and perform quantitative analysis.

Summary: The development and application of fraction collection in preparative supercritical fluid chromatography (SFC) are discussed in this review. Various devices for separating the carbon dioxide mobile phase from the analyte and the modifier, as well as techniques for controlling fractionation, are described. The applications of fraction collection, including two-dimensional chromatography and supercritical fluid extraction coupled with SFC, are also discussed.

Summary: Multi-stage fractionation of pine bark was conducted using subcritical and supercritical CO2, with an additional extraction using ethanol to recover extracts enriched with phenolics and glycerol. Different compounds families were recovered in each step, and a full characterization was achieved using high-temperature GC-MS/FID with four internal standards.

Summary: The propagation of flames in non-homogeneous medium was studied for the combustion of methane with oxygen at high pressure in supercritical regime. Simulations were conducted using a reduced chemistry model and high fidelity simulations. The results showed the formation of triple flames along the stoichiometric isoline with the addition of a hot spot, regardless of the configuration. The addition of homogeneous isotropic turbulence promoted combustion and increased the length of the flame in the case of a pocket of methane, while finger-like structures and non-premixed combustion were observed in the splitter plate configuration.

Summary: Accurate information on the galactose content in commercial agro-food resources is essential for patients with galactosemia. This study used gas chromatography to analyze the galactose content in 107 Korean agro-food resources and found that steamed barley rice had a higher galactose content compared to other types of rice. Sweet potatoes, zucchini, and Kabocha squash had high galactose content, while mushrooms, meat, and aquatic products showed low galactose content. These findings are important for managing galactose intake in patients.

Summary: The study quantified the distribution of methanol and formic acid in body fluids and tissues from deceased victims of industrial alcohol poisoning. Correlations were found between the concentrations of methanol and formic acid in various biological samples. These results are valuable for toxicological analysis and improving medical standards.

Summary: This study investigated the potential of using supercritical fluid extracts from Matricaria chamomilla white ray florets as a source of bioactive cosmetic ingredients. The extracts contained a diverse range of phytochemical classes and had cytotoxic, proliferation-reducing, and antimicrobial activities, making them potentially useful in cosmetic formulations.

Summary: In this study, the high-temperature combustion chemistry of tetrahydrofurfuryl alcohol (THFA), a THF based biofuel, was investigated using experimental and numerical methods. More than 40 chemical products were identified and quantified, with a detailed kinetic model for THFA combustion developed. The study successfully predicted the experimental data and revealed the main consumption pathways and product formation mechanisms of THFA.

Summary: The study demonstrates the potential of supercritical extracts from Achillea millefolium and Rosa canina herbal dust as a source of valuable compounds, with lower pressures yielding higher compound recoveries. The major compounds in the mixtures were oxygenated monoterpenes and sesquiterpene hydrocarbons.
