Summary: A mathematical model was constructed to analyze the energy metabolism in erythrocyte-bioreactors containing alcohol dehydrogenase and acetaldehyde dehydrogenase. These erythrocytes can convert ethanol to acetate and potentially be used for alcohol intoxication treatment. The analysis revealed that the rate of ethanol consumption by the erythrocyte-bioreactors increases until a specific threshold level of enzyme activity is reached. Beyond this threshold, the model switches to an oscillation mode, leading to the accumulation of glycolytic intermediates and the destruction of erythrocyte-bioreactors.

Summary: In this study, DBSA was utilized as an efficient catalyst for synthesizing oleic acid-based wax esters under solvent-free conditions at 40 degrees C. The optimal conditions yielded a 93.6% conversion rate of cetyl alcohol, with factors such as molar ratio, reaction temperature, and reaction time playing crucial roles. Water content was found to have an inhibitory effect on esterification, which decreased significantly with increasing temperature. DBSA-catalyzed low-temperature esterification proved to be an efficient method for producing liquid wax esters.

Summary: In this study, the behavior of oleic acid and 9/10-nitro oleic acid at a polarized water-1,2-dichloroethane interface was investigated. Both fatty acids can undergo an interfacial ion transfer reaction mainly limited by diffusion. The results showed similar acid-base properties and water solubility for both fatty acids, with 9/10-nitro oleic acid being slightly more hydrophilic and forming supramolecular structures.

Summary: This study optimized and evaluated self-assembled liquid crystalline nanoparticles (SALCs) to enhance the absorption of omega-3s. The study found that the structure and formulation of SALCs played a crucial role in improving the dissolution, permeation, and oral bioavailability of omega-3. The dissolution rates of omega-3 SALCs were 1.7 to 2.3-fold higher than those of the reference Omacor soft capsules, and the oral bioavailability of omega-3 in SALCs was increased by 2.5-fold for EPA and 3.1-fold for DHA compared to the reference. The study provides a novel formulation that improves the bioavailability of EPA and DHA by spontaneously forming liquid crystal-based nanoparticles.

Summary: This study investigated the effects of adding oleic acid on the metabolic flux distribution of ganoderic acids R, S and T's biosynthesis from Ganoderma lucidum. The results showed that adding filter-sterilized oleic acid during submerged fermentation and static culture enhanced the synthesis and content of ganoderic acids R, S and T. It also improved the overall metabolic flux distribution of G. lucidum and reduced the accumulation of by-products. This study provides an important foundation for improving triterpene production in the submerged fermentation of G. lucidum.

Summary: This study aimed to optimize the reaction conditions for the catalytic epoxidation of palm oleic acid, resulting in a maximum relative conversion to oxirane of 85.6% under the determined optimum conditions. A mathematical model was developed using MATLAB software, integrating the fourth-order Runge-Kutta method with the genetic algorithm to determine the reaction rate that fit with the experimental data. The study successfully transformed palm oleic acid into an epoxide, demonstrating the potential for promoting palm oil base utilization as raw material.

Summary: This study found that lymphangiogenesis occurs in tumor lesions and surrounding adipose tissue, and the density of lymphatic vessels is correlated with an increase in circulating free fatty acids in the lymph of tumor-bearing mice. Adipocyte-released FFA can stimulate the sprouting of lymphatic endothelial cells, with monounsaturated oleic acid playing a key role in the promotion of lymphangiogenesis in the tumor microenvironment.

Summary: The present research used numerical simulation by computational fluid dynamics to study, predict, and understand the migration of benzene during an industrial spill. The main mechanisms considered were advection, diffusion, and adsorption. The spill occurred due to a fracture under a fuel oil storage tank, with an initial benzene concentration of 60 ppm. Samples taken from the affected zone showed concentrations of benzene exceeding the Mexican Official Standards (MOSs) of 15 ppm. The numerical simulation estimated that the spill began approximately 2 years ago, and it predicts that the MOSs concentration will be reached in 14 years.
