Effect of three-dimensional to one-dimensional orientation of cellulose nanofiber sizing agents on carbon fibers under magnetic and electric fields on composite material properties.

Nanoparticle-containing sizing agents are essential for the overall performance of high-quality carbon fiber (CF) composites. However, the uneven dispersion of nanoparticles often leads to agglomeration on the surface of CF after sizing, consequently diminishing the material properties. In this study, the properties of cellulose nanofibers (CNFs) that can respond to magnetic and electric fields were utilized to achieve three-dimensional to one-dimensional orientations in CFs containing sizing agents.

Growth of ZnO nanorods/flowers on the carbon fiber surfaces using sodium alginate as medium to enhance the mechanical properties of composites.

The chemical inertness of the carbon fiber (CF) surface results in suboptimal mechanical properties of the prepared composites. To address this issue, we employed a combination of tannic acid and 3-aminopropyltriethoxysilane mixture (TA-APTES) grafted sodium alginate (SA) as a medium to enhance the interfacial properties of composites through the growth of ZnO nanoparticles on CF surfaces. ZnO nanolayers with rod-like and flower-like structures were obtained by adjusting the pH of the reaction system (pH = 10 and 12, respectively).

Pharmacokinetics and molecular docking of the cardioprotective flavonoids in Dalbergia odorifera.

The purpose of this research was to investigate the cardioprotective effects and pharmacokinetics of Dalbergia odorifera flavonoids. The cardioprotective effects were detected by hematoxylin-eosin staining histopathological observations and the detection of myocardial enzymes by kits in serum, peroxidation and antioxidant levels and ATPase activities by kits in the homogenate supernatant, and antioxidant and apoptosis-related protein expression in heart tissue by immunohistochemistry. The pharmacokinetics parameters of the flavonoids in rat plasma were investigated by ultra-high-performance liquid chromatography coupled with tandem mass spectrometry.

Agarwood extract mitigates alcoholic fatty liver in C57 mice via anti‑oxidation and anti‑inflammation.

Alcoholic fatty liver disease (AFLD) is a disease with a high incidence rate among individuals who drink alcohol. Our previous study found that agarwood alcohol extracts (AAEs) have a protective effect against drug‑induced liver damage via anti‑inflammatory and antioxidant mechanisms. Therefore, we hypothesized that agarwood may have a protective effect against AFLD.

[Anxiolytic and antidepressant effects of agarwood inhalation and its mechanism].

This study used m-chloropheniperazine(MCPP) and chronic unforeseeable mild stress(CUMS) to induce the rat models of anxiety and depression, respectively. The behaviors of rats were observed by the open field test(OFT), light-dark exploration test(LDE), tail suspension test(TST), and forced swimming test(FST), and the antidepressant and anxiolytic effects of agarwood essential oil(AEO), agarwood fragrant powder(AFP), and agarwood line incense(ALI) were explored. The enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of 5-hydroxytryptamine(5-HT), glutamic acid(Glu), and γ-aminobutyric acid(GABA_A) in the hippocampal area.

Agarwood essential oil inhalation exerts antianxiety and antidepressant effects via the regulation of Glu/GABA system homeostasis.

Depression and anxiety are common diseases that endanger the physical and mental health of individuals. Agarwood incense inhalation has been used as a traditional Chinese medicine for relaxation and to improve sleep for centuries. In a previous study by the authors it was demonstrated that agarwood essential oil (AEO) injection exerted anxiolytic and antidepressant effects.

Effective Components and Molecular Mechanism of Agarwood Essential Oil Inhalation and the Sedative and Hypnotic Effects Based on GC-MS-Qtof and Molecular Docking.

Agarwood has been used for the administration of hypnotic therapy. Its aromatic scent induces a relaxed state. However, its aromatic constituents and the underlying molecular effect are still unclear.

Multi-residue analysis of 26 organochlorine pesticides in Alpinia oxyphylla by GC-ECD after solid phase extraction and acid cleanup.

A simple and effective multi-residue method was developed and validated for the analysis of 26 organochlorine pesticide residues in Alpinia oxyphylla by a gas chromatography with an electron capture detector (GC-ECD). The target pesticides were extracted by sonication and cleaned up with florisil solid phase extraction and sulphuric acid. Some crucial parameters, including extraction solvent and time, sorbent type, elute solvent and concentration of sulphuric acid were optimized to improve the performance of sample preparation procedure.

Rapid analysis of multi-pesticides in Morinda officinalis by GC-ECD with accelerated solvent extraction assisted matrix solid phase dispersion and positive confirmation by GC-MS.

In this work, 33 organochlorine pesticides (OCPs) and 9 pyrethroid pesticides (PYPs) in Morinda officinalis were effectively and selectively extracted and cleaned up by accelerated solvent extraction assisted matrix solid phase dispersion (ASE/MSPD) method, followed by gas chromatography-electron capture detection (GC-ECD). Carbophenothion was selected as the internal standard and added into the final extracts to improve the precision and accuracy of the method. Parameters for ASE/MSPD procedure including ratio of acetone to n-hexane, temperature and amount of Florisil were optimized to improve the performance of the method through orthogonal experimental design.

Streamlined pretreatment and GC-FPD analysis of multi-pesticide residues in perennial Morinda roots: a tropical or subtropical plant.

In this study, a simple and rapid multi-pesticide residues analytical method has been developed and evaluated for simultaneous identification and quantification of 30 organophosphorus pesticides (OPPs) present at trace levels in perennial Morinda roots. Samples were firstly extracted and cleaned up with a streamlined method (modified QuEChERS), and then detected by gas chromatography with flame photometric detector (GC-FPD). For accurate quantification, representative matrix-matched calibration curves were applied to compensate matrix effects.
