Summary: In recent years, there has been an increasing interest in using natural antioxidants from apples and apple by-products as alternatives to synthetic additives in food products. Studies have found that ultrasound-assisted extraction is the most promising technique for obtaining high yields of phenolic compounds from apples. Green technologies such as supercritical fluid extraction, with the use of a co-solvent, have also shown promising results. Furthermore, recent studies have indicated the feasibility of utilizing these compounds in food products and packaging materials.

Summary: Natural products and their derivatives are widely used in various industries, especially pharmaceuticals. Modern engineered biosynthesis offers an alternative approach for producing diverse natural products. However, natural enzymes often exhibit unsatisfactory catalytic characteristics and require further enzyme engineering modifications. QM/MM, a computational tool extensively used in enzyme catalysis, has been increasingly applied in rational enzyme engineering for natural product biosynthesis. This review summarizes recent advances in QM/MM computational investigation on enzyme catalysis and enzyme engineering and discusses the challenges and perspectives for future QM/MM-assisted enzyme engineering in natural product biosynthesis.

Summary: Psychological research often aims to find general rules that apply to everyone, but this conflicts with the examination of individual uniqueness. While there are general statistical regularities in subjective self-report data, which can be used with statistical and psychometric methods, there has been a neglect of individual-specific data. This paper reviews the method of derangements as a way to analyze idiographic data and discusses its potential for research and practice.

Summary: Natural products are widely used in industry, food, and therapy. Characterizing them chemically is vital to explore their potential applications. Microextraction techniques, which use less organic solvents and sample amount compared to classical techniques, have gained popularity but are still less used in natural product analysis. This manuscript reviews popular solid-based miniaturized sample preparation techniques and discusses their advantages, disadvantages, and main applications in determining compounds in natural products.

Summary: The study highlights the potential of flow-cell reactors in enhancing the efficiency of CO2 reduction reaction, but emphasizes the need for a standard testing methodology to ensure accurate product detection and fair performance comparisons. Through systematic experiments, the study identifies commonly overlooked factors in product measurements and proposes a modified testing system for accurate assessment of CO2RR products in flow cells.

Summary: A new composite material, Rt/MAn, was synthesized by impregnating rutile (TiO2) nanoparticles (Rt) into H2O2-modified anthracite (MAn), showing a high removal efficiency for malachite green (MG) dye. The adsorption process was well described by the Freundlich equation and a multilayer statistical physics model, with adsorption energy being primarily governed by physical interactions. Rt/MAn demonstrated excellent reusability with over 80% of MG adsorption capacity retained even after five cycles.

Summary: This study investigated the use of natural deep eutectic solvents (NADESs) in combination with microwave-assisted extraction (MAE) for the optimal extraction and enhanced antioxidant activity of bioactive compounds from date seed powder (DSP). The two most efficient NADESs, choline chloride-lactic acid (ChCl-LA) and choline chloride-xylose (ChCl-Xylo), were further optimized using response surface methodology (RSM). The optimized conditions resulted in significantly increased values for FRAP, DPPH, and TPC, indicating the enhanced yield of bioactive compounds. The synthesized NADESs have the potential to replace conventional solvents in various industries as green and safe ingredients.

Summary: Preliminary analyses show significant and temporary drops in NO2 and CO levels at ground-based measurement sites in Southern Ontario during lockdowns due to COVID-19, while fewer sites experienced statistically significant decreases in O3 and PM2.5 levels. Developing a statistical protocol that accounts for various factors such as seasonal variability and new influences like COVID-19 restrictions highlights the importance of a rigorous assessment of statistical significance for informing policy decisions.

Summary: This review focuses on the antiobesity effects of natural product extracts, including extraction methods, bioactive ingredients, and mechanisms. Natural product extracts exert antiobesity effects through multiple mechanisms, but further evaluation is needed. Improving the bioavailability and determining effective and safe human doses of these bioactive ingredients should be a priority for future research.

Summary: An environmentally friendly method using natural deep eutectic solvents (NADES) and microwave-assisted extraction (MAE) was developed for the recovery of bioactive compounds from hazelnut pomace. The most suitable NADES for extracting antioxidants from hazelnut pomace was choline chloride:1,2-propylene glycol (CC-PG). Under optimized conditions, extracts of both hazelnut pomace and unprocessed hazelnut flours exhibited higher antioxidant capacities compared to ethanolic extracts. The results suggest that hazelnut by-products can serve as a valuable source of natural antioxidants and the MAE procedure has potential applications in pharmaceutical and food industries.

Summary: Recently, there has been an increasing demand for products enriched with natural compounds that benefit human health. Black rice and its by-products contain high amounts of anthocyanins, which have various potential health benefits such as anti-obesity, antidiabetic, antimicrobial, anticancer, neuroprotective, and cardiovascular effects. Extracts from black rice and its by-products have great potential for application in functional foods, supplements, and pharmaceutical formulations. This overview summarizes the methods used for anthocyanin extraction from black rice and its by-products, as well as the trends in their biological applications. Common extraction methods include maceration, ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE). Anthocyanin-rich extracts from black rice show promising biological potential, particularly in anti-cancer properties. However, more clinical trials are needed to validate these effects. Extracts from black rice and its by-products can be utilized to develop functional products for human consumption while reducing agro-industrial waste.

Summary: With the increasing strictness of environmental protection policies in China, coal-fired power plants have widely adopted air pollution control devices, especially selective catalytic reduction (SCR). This study successfully developed an on-line coupling system based on atomic fluorescence spectrometry (AFS) and a homemade chromatographic workstation to identify mercury (Hg) species through thermal programmed desorption (TPD). The main species in fly ash were HgCl2 and HgO, while in gypsum they were Hg2Cl2 and HgO. The study demonstrated that AFS coupled with TPD was an effective method to analyze Hg species in coal combustion by-products from power plants.

Summary: This study presents a thermodynamic evaluation of using a Reciprocating Expansion Engine (REE) to recover pressure exergy in the Natural Gas (NG) distribution network. The GERG-2008 equation of state (EOS) and the Try & Error method, as well as an Artificial Neural Network (ANN) method, are used to simulate the REE and evaluate its performance. The results show that the NG composition has a significant impact on the REE performance.

Summary: Different surface modifications of PCL fiber mats influence the binding and release of BMP-2, with polydopamine coating showing the highest binding capacity. Functionalization with chitosan nanogel considerably increases BMP-2 binding on all hydrophilized surfaces and results in sustained release without loss of bioactivity.

Summary: The plant microbiota in paddy soil can influence plant health and fitness by promoting methylmercury (MeHg) production. However, the effect of rice rhizosphere assemblages on MeHg production remains unclear. This study used network analyses of microbial diversity to investigate the bacterial networks in bulk soil, rhizosphere, and roots during rice development at different Hg gradients. The results showed that Hg gradients significantly affected the niche-sharing of taxa related to MeHg/THg, while plant development had minimal effect. The complexity and connectivity of root microbial networks increased with an Hg concentration of 30 mg kg-1 in the soil.
