Summary: The aim of this study was to assess the exposure to Toluene in the paint industry and evaluate the environmental and biological monitoring techniques. Air and biological samples were collected from workers in two factories, and the results showed high exposure levels to Toluene. The correlation between the biomarker HA and air concentrations was the strongest.

Summary: This study aimed to identify the factors that may affect the biological monitoring of benzene, toluene, and xylene (BTX) metabolites. The results showed significant differences in the levels of biomarkers between the exposed and non-exposed groups. The regression model demonstrated that level of education, work experience, residence, length of work per shift, use of personal protective equipment (PPE), and consumption of industrial food or fruit juice significantly affected the biomarker levels.

Summary: The study found that batik workers exposed to toluene had higher levels of urinary hippuric acid compared to non-batik workers. Workers with longer working periods, those performing writing tasks, and stamping workers were more likely to have higher concentrations of uHA. Additionally, workers exhibiting symptoms of toluene exposure also showed higher uHA concentrations.

Summary: Ultrasound-assisted extraction is effective for extracting natural antioxidants. Different roasting levels of Arabica coffee beans were extracted using UAE, with significant differences in physicochemical and biological characteristics observed based on roasting and extraction conditions. Roasting process affects the contents of caffeine and chlorogenic acid in coffee beans.

Summary: Mexico is known for its specialty and organic coffee, mainly produced by small indigenous community cooperatives. The physical, chemical, and biological characteristics of different roasts of Coffea arabica varieties were analyzed. The study found that the caffeine and melanoidin contents increased with the level of roasting, while the chlorogenic acid content showed a dissimilar effect. Premium and specialty coffees were classified based on their nutritional content and sensory evaluation.

Summary: This study presents a simple, sensitive, and validated method for determining the content of chlorogenic acid in green and roasted coffee, without the need for chromatographic separation. The method utilizes luminescence intensity quenching to measure the concentration of chlorogenic acid. The results showed that the method is effective and can be applied for quality control of chlorogenic acid in coffee.

Summary: This review discusses the epigenetic effects of coffee extract and its three essential active ingredients (caffeine, chlorogenic acid, and caffeic acid). Coffee, as a popular beverage, contains active ingredients with various biological functions such as insulin sensitization, improvement of sugar metabolism, antidiabetic properties, and liver protection. However, recent studies have shown that coffee can have both beneficial and detrimental effects on human health due to its complex components. It has been found that coffee extract and its components can potentially influence gene expression through epigenetic modifications, such as DNA methylation, histone modifications, and ncRNA expression, which can have long-lasting impacts on the epigenome. Importantly, the consumption of coffee during pregnancy has been associated with negative effects on offspring due to epigenetic modifications, while it has also been linked to improvements in various diseases, including cancer. Therefore, understanding the epigenetic effects associated with coffee components is crucial for improving human health.

Summary: The study found that coffee stems accumulate multiple compounds, such as chlorogenic acid, vanillin, and resveratrol, with their presence depending on the type of fertilization. Optimal performance was observed at the highest concentration tested (500 μg/mL) in all samples, with doses of 70% and 100% showing the best values for most concentrations. This highlights the potential for reuse of coffee stem residues as profitable antioxidant material.

Summary: Coffee is a popular and widely consumed beverage worldwide, with potential health benefits such as reduced risks of cardiovascular disease, cancers, and liver disease. This study focuses on investigating the health effects and potential applications of spent coffee grounds (SCG), which contain bioactive compounds similar to coffee and have shown positive effects on metabolic parameters, gut microbiome, and energy consumption. SCG utilization could also contribute to reducing global waste from coffee production. Overall, SCG shows promise in moderating chronic human diseases and decreasing environmental impact.

Summary: A factorial design study using asparaginase treatment on arabica coffee beans showed a reduction in acrylamide content with the enzyme load, hydrolysis time, and water content as key factors. Statistical analysis revealed the importance of steam pretreatment for coffee beans, and the optimal conditions for reducing acrylamide content were identified. Asparaginase treatment did not impact the major bioactive compounds in coffee.

Summary: Selection of plant extracts as bioactive phytochemical source to synthesize nanoparticles is highly demanding due to their biocompatibility, nontoxicity, and cost-effectiveness. In this study, Coffee arabica leaf extracts (CAE) were used to produce highly stable silver nanoparticles (AgNPs), and the mechanism of bio reduction, capping, and stabilization mediated by 5-caffeoylquinic acid (5-CQA) is discussed. The green synthesized NPs were characterized using various techniques, and the affinity of 5-CQA capped CAE-AgNPs for thiol moiety of amino acid was utilized for sensitive detection of L-cysteine (L-Cys).

Summary: Coffee contains various bioactive components that are beneficial for human health, such as caffeine, polyphenols, and alkaloids. Research suggests that regular coffee consumption can reduce the risk of cardiovascular diseases, type 2 diabetes, obesity, and certain types of cancer, while also potentially lowering the risk of neurodegenerative conditions like Alzheimer's and Parkinson's diseases. Further studies are needed to fully understand the mechanisms behind these effects and the therapeutic applications of coffee bioactive components.
