Summary: The study investigated the caffeine content and phenolic profile of different types of teas and coffees with two successive extractions. Green tea showed high flavanol content in the second extraction, while mate tea's phenolic acid content increased. Black tea had the highest caffeine content in both extractions, and water was the most effective solvent in most cases for extracting these compounds.

Summary: This study focuses on the design of green solvent production of ethyl lactate, including conventional reactive distillation design and three designs of reactive distillation column (Design-1, Design-2, and Design-3). The binary interaction parameters from three thermodynamic models (UNIQUAC, UNIFAC, NRTL) were validated. Process simulation and economic evaluation were conducted using Aspen Plus. The results showed that Design-1 is the optimal solution, reducing the total capital cost by 57.3% and the total operating cost by 17.5%.

Summary: A large prospective cohort study in the United States found an inverse association between pneumonia and influenza deaths and coffee intake. In Japan, where the mortality rate of pneumonia in elderly people is high, a hospital-based case control study investigated the association between coffee and green tea intake and pneumonia among the elderly. The study suggested a preventive association between coffee intake over 2 cups per day and pneumonia in the elderly.

Summary: Patients with Crohn's disease and ulcerative colitis are at higher risk of osteoporosis due to lower bone mineral density. Risk factors are divided into unmodifiable (age, gender, genetic factors) and modifiable (diet, physical activity, stimulants). Compounds in coffee and tea can affect bone metabolism, either protecting or increasing bone resorption. The impact of coffee and tea on inflammatory bowel diseases remains contradictory.

Summary: In this study, it was found that green tea nanoparticles (gTNPs) could form a ternary aggregate with epigallocatechin gallate (EGCG) and caffeine (CAF) complexes, playing a role in tea cream formation. The interaction between gTNPs and EGCG-CAF complexes was dominated by hydrophobic interaction at low zeta-potential conditions.

Summary: Despite advancements in surgery and therapies, small cell lung cancer (SCLC) remains one of the deadliest types of cancer. A metabolic precision approach for SCLC patients is proposed for the first time, highlighting the importance of metabolic health and lipid gene expression in predicting SCLC survival. Two lipid metabolism genes, racemase and perilipin 1, along with a genetic risk score of both genes, are shown to be biomarkers of SCLC survival. Importantly, controlling metabolic health, lipid gene expression, and lifestyle-associated environmental factors is crucial for increased SCLC survival.

Summary: Using eggshell-derived CaO heterogeneous catalyst for the synthesis of glycerol carbonate (GC) from glycerol and dimethyl carbonate (DMC) showed promising results in terms of mass transfer enhancement and energy efficiency. By utilizing a simple kitchen countertop blender, it was possible to overcome mass transfer limitations and achieve higher conversion rates and reaction efficiency. This study also highlighted the potential of self-frictional heat generation for heat transfer intensification, leading to a more homogeneous distribution in the reaction system.

Summary: Glycerol carbonate (GC) was successfully synthesized using calcium oxide (CaO) derived from eggshell as a catalyst in transesterification reaction. The catalyst showed deteriorated performance upon recycling due to phase transformation to CaCO3, resulting in decreased catalytic activity. The mechanism of CaO catalyzed transesterification and catalyst deactivation were proposed and demonstrated.

Summary: This study aimed to develop a model based on commonly requested hematological variables for early discrimination of patients with COVID-19 from those with other viral pneumonia. It identified 10 variables for the characterization of COVID-19 and found that low levels of leukocytes could serve as a primary marker for COVID-19 detection. The results suggest that commonly requested laboratory variables can help distinguish COVID-19 and stratify patients.

Summary: The olive oil industry produces a large amount of olive stones annually, which can be used as biofuel but their high oil content affects combustion. Olive stones also contain valuable antioxidants, which can generate additional revenue for the biofuel industry. This study investigates the extraction of antioxidants and their activity using different solvents, as well as the effect of gastrointestinal digestion on the antioxidant content. The extract obtained with 50% aqueous ethanol showed the highest antioxidant activity, but the activity decreased after digestion.

This study found that spent coffee grounds can serve as a support material for Chlorella vulgaris sp. microalgae, enhancing the attached microalgal growth. Additionally, a specific photoperiod regime with a dark period cycle of 4 hours per day resulted in the maximum microalgal density, allowing the attached microalgae to strengthen their mixotrophic growth and accumulate a significant amount of lipid.

In this study, the high-pressure behavior of components in a cyclic carbonate synthesis process directly from CO2 and bio-based alcohols was investigated. The solubility of certain compounds in the CO2-rich phase was determined, and the influence of an ionic liquid as a solvent on solubility was examined. This knowledge will be valuable for designing chemical conversions of carbon dioxide.

Summary: Microwave and ohmic heating are popular choices for aseptic processing due to their rapid heating capabilities and better product quality. This study aims to find an alternative approach to simulate processing conditions by modeling and validating the process using surrogate particles and microorganisms. A mathematical model was used to simulate heat transfer in fluid and solid particles. The process was validated using simulated particles and surrogate microorganisms, with magnetic implants in spherical particles to measure residence time distribution. The microwave aseptic system was successfully validated for producing shelf-stable particulate food products.
