Freeze drying and spray drying for the retention of the active components, L‐theanine and caffeine, and antioxidant activity of tea‐based ingredients

SummaryPreserving food products from oxidation improves their quality and stability. This study compares the effects of storage on L‐theanine, caffeine, moisture content and antioxidant activity of spray‐dried and freeze‐dried white tea infusions. The antioxidant activities of both dried infusions were restored over a 60‐day storage. On Day 60, the L‐theanine and caffeine levels of the freeze‐dried samples were respectively 1.45 ± 0.03 mg mL−1 and 2.23 ± 0.04 mg mL−1 compared with 1.16 ± 0.03 mg mL−1 and 1.97 ± 0.01 mg mL−1 on Day 0. In the spray‐dried samples, the L‐theanine was 0.32 ± 0.01 mg mL−1 on Day 60 and 0.36 ± 0.02 mg mL−1 on Day 0, while caffeine remained unchanged. Regarding undried/control samples, L‐theanine and caffeine declined from respectively 0.29 ± 0.0004 mg mL−1 and 0.33 ± 0.01 mg mL−1 on Day 0 to 0.2 ± 0.001 mg mL−1 and 0.26 ± 0.02 mg mL−1 on Day 60, associated with a decrease in DPPH activity from 75.87% (Day 0) to 15.34% (Day 60). Freeze‐drying and spray‐drying tea infusions yielded functional products with stable antioxidant activity and moisture. Both drying techniques are reliable for preserving tea preparations.

Inhibiting Effect and Mechanism of Aconitum tanguticum (Maxim.) Stapf on Intestinal Fibrosis of CCD-18Co Cells

Abstract Objective: The objective of the study was to explore the potential signaling mechanism of Aconitum tanguticum (Maxim.) Stapf (ATS) and its impact on intestinal fibrosis in vitro. Methods: Network pharmacology was used to screen the active components of ATS and predict their potential targets in intestinal fibrosis. The protein–protein interaction network graph was constructed using drug–disease intersection targets retrieved from the Search Tool for Retrieval of Interacting Genes/Proteins database. The network diagram was analyzed using Cytoscape 3.6.1’stopology function. The gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were conducted using the database for annotation, visualization, and integrated discovery platform. Intestinal fibroblast model in vitro was constructed using transforming growth factor-β1 (TGF-β1)-induced CCD-18Co cells. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to verify the network pharmacology-predicted antifibrotic signaling pathway of ATS and the traditional antifibrotic signaling pathway. Results: Network pharmacology revealed that there were 19 active components in ATS, suggesting that ATS could be involved in the regulation of mitogen-activated protein kinase 1 (MAPK1), PIK3CA, MAPK3, and other important targets that are present in cancer pathways, including proteoglycans, influenza A, and phosphatidylinositol-3-kinase (PI3K)-protein kinase B (Akt) signaling pathways. The results of quantitative reverse transcription-polymerase chain reaction (qRT-PCR) demonstrated that 0.1–1 μg/mL ATS may suppress tissue inhibitor of metalloproteinase 1, collagen I, and alpha-smooth muscle actin expression levels. The expression of the TGF-β/suppressor of the mother against decapentaplegic (Smad) and PI3K/Akt signaling pathways was controlled by ATS. In addition, ATS inhibited the PI3K/Akt pathway by reducing the expression of MAPK1, HSP90AA1, and PIK3CA. Conclusions: It has been confirmed that ATS is a multipathway and multitarget treatment for intestinal fibrosis. This study suggested that ATS might alleviate intestinal fibrosis by blocking both the TGF-β/Smad and the PI3K/Akt pathway.

Fuzheng Touxie Jiedu Huayu Decoction inhibits the MexAB-OprM efflux pump and quorum sensing-mediated biofilm formation in difficult-to-treat multidrug resistance Pseudomonas aeruginosa

Ethnopharmacological relevanceFuzheng Touxie Jiedu Huayu Decoction (FTJHD) is a commonly used clinical formula that has been found effective in resisting multidrug resistance-Pseudomonas aeruginosa in previous in vivo and in vitro studies. Aim of the studyTo investigate the antimicrobial effects of FTJHD and its drug-containing serum alone or in combination with ceftazidime on difficult-to-treat multidrug resistance-P. aeruginosa (DTMDR-P. aeruginosa). Materials and methodsThe antibacterial effects of FTJHD and its drug-containing alone or in combination with ceftazidime against DTMDR-P. aeruginosa were examined by the tube dilution method and bacterial growth curves. The changes in the bacterial ultrastructure were examined by transmission electron microscopy. The biofilm formation ability of bacteria was examined by crystal violet staining and scanning electron microscopy. The expression of the MexAB-OprM efflux pump and quorum sensing system genes were validated through quantitative polymerase chain reaction. Molecular docking was used to evaluate the interaction between active components and the MexAB-OprM efflux pump. ResultsFTJHD-containing serums at 1-, 2-, 4-, and 8-fold concentrations reduced the minimal inhibitory concentration (MIC) of ceftazidime against DTMDR-P. aeruginosa from 128 μg/mL to 64 μg/mL. Sub-inhibitory concentrations of ceftazidime in combination with FTJHD and FTJHD-containing serum prolonged the lag period of bacterial growth and reduced bacterial numbers. Additionally, 1/2 MIC of ceftazidime combined with FTJHD-containing serum significantly inhibited the activity of the MexAB-OprM efflux pump and quorum sensing system, thus reducing biofilm formation while causing more severe damage to the bacteria. Molecular docking revealed a strong affinity of quercetin, baicalein, luteolin, kaempferol, and β-sitosterol for the efflux pump regulatory proteins OprM and MexR. ConclusionFTJHD can exert synergistic anti-DTMDR-P. aeruginosa effects with ceftazidime by inhibiting biofilm formation mediated by the MexAB-OprM efflux pump and quorum sensing.

Study on the bioactive ingredients and mechanism of Huangqi against diabetic retinopathy based on network pharmacology and experimental verification.

Diabetic retinopathy (DR) is one of the most well-known microvascular complications of diabetes mellitus. As a traditional Chinese medicine, Huangqi (HQ), has been used for treating DR for a long time. However, its anti-DR active ingredients and mechanism are still unknown. Therefore, we designed this study to explore the active components and mechanism of HQ against DR via network pharmacology analysis. The ingredients of HQ, potential targets of HQ and DR were obtained from public databases. We employed the protein-protein interaction (PPI) network, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment and Gene Ontology (GO) analysis to identify core targets and pathways of HQ against DR. Finally, molecular docking and vitro experiments were applied to validate our results. A total of 34 potential targets of HQ against DR were obtained. Based on PPI network, VEGFA, PTGS2, IL6 and CCL2 were considered as core targets. GO analysis involved 692 biological processes, 21 cellular components and 35 molecular functions. KEGG enrichment analysis manifested that the anti-DR effect of HQ was mainly mediated via the AGE-RAGE signaling pathway in diabetic complications. The molecular docking results indicated that kaempferol had higher affinity with CCL2, IL-6, VEGFA and PTGS2. The vitro experiments showed that the mRNA expressions of CCL2, IL-6, VEGFA and PTGS2 in ARPE-19 cell were differentially decreased after kaempferol treatment. This study preliminarily unveiled that the therapeutic efficacy of HQ against DR might be attributed to the reduced expression of CCL2, IL-6, VEGFA and PTGS2.

Rapid Classification and Identification of Chemical Compounds and Semi-Quantitative Metabolism of Huangkui Capsules and the Protective Effects of Its Quercetin Derivatives against Tacrolimus-induced HK-cell Reduction

Abstract Objective: The study aimed to establish an effective strategy for systematically characterizing and verifying compounds in Huangkui capsules (HKCs). Materials and Methods: An ultrahigh-performance liquid chromatography quadrupole time-of-flight mass spectrometry (MS) method was effectively established and utilized for the chemical compound characterization in HKC, with the support of MS-DIAL, MS-FINDER, and Global Natural Product Social Molecular Network. Multiple rat samples were analyzed after the oral administration. Metabolites were identified based on specific cleavage behaviors, and metabolic pathways were predicted. Semi-quantitative analysis of the metabolome profiles was conducted using post-data processing. High concentrations in vivo were investigated for their role in tacrolimus-induced death of HK-2 cells. Results: In total, 129 compounds were identified in HKC, of which 74 were reported for the first time. In this study, we successfully identified and uncovered 19 prototypes and 123 metabolites from the biosamples. The concentrations of glucuronidation and methylation metabolites of quercetin were the highest in the kidney and intestinal tissues. In contrast, significant glucuronidation of quercetin metabolites was observed with high blood concentrations. Notably, quercetin glucuronidation and methylation metabolites protected HK-cell against tacrolimus-induced injury in a dose-dependent manner. Conclusion: This study successfully established a reliable and efficient strategy for comprehensive characterization of traditional Chinese medicine compounds. This strategy harnessed the power of various intelligent postprocessing technologies to provide a more thorough understanding of active components and their metabolic transformations in the body. These results suggest that quercetin metabolites should be evaluated for their protective capacity against kidney disease.

Inhibition of Glycyrrhiza Polysaccharide on Human Cytochrome P450 46A1 in vitro and in vivo: Implications in Treating Neurological Diseases.

Cytochrome P450 (CYP) 46A1, also known as cholesterol 24S-hydroxylase, is essential for maintaining the homeostasis of cholesterol in the brain and serves as a therapeutic target of neurodegenerative disorders and excitatory neurotoxicity. N-methyl-d-aspartate receptor (NMDAR) is a prototypical receptor for the excitatory neurotransmitter glutamate and can be specifically regulated by 24S-hydroxycholesterol (24S-HC). Glycyrrhiza is one of the most widely used herbs with broad clinical applications. It has several pharmacological activities, such as clearing heat and detoxifying, moistening the lung and relieving cough, analgesic, neuroprotective outcomes, and regulating a variety of drug activities. Glycyrrhiza is a commonly used herb for the treatment of epileptic encephalopathy. However, whether glycyrrhiza can interfere with the activity of CYP46A1 remains unknown. This study aimed to investigate the regulating effects of glycyrrhiza polysaccharides (GP) on CYP46A1-mediated cholesterol conversion, as well as in the modulation of related proteins. The effects of glycyrrhiza polysaccharide (GP) on the activity of CYP46A1 were investigated in vivo and in vitro. Moreover, the potential regulatory effects of GP on the expressions of CYP46A1, HMG-CoA reductase (HMGCR), and NMDAR were also detected. The in vitro results demonstrated that glycyrrhiza polysaccharide (GP), as the main water-soluble active component of glycyrrhiza, remarkably inhibited the activity of CYP46A1 in a non-competitive mode with a Ki value of 0.7003 mg/ml. Furthermore, the in vivo experiments verified that GP markedly decreased the contents of 24S-HC in rat plasma and brain tissues as compared to the control. More importantly, the protein expressions of CYP46A1, GluN2A, GluN2B, and HMG-CoA reductase (HMGCR) in rat brains were all downregulated, whereas the mRNA expressions of CYP46A1 and HMGCR were not significantly changed after treatment with GP. GP exhibits a significant inhibitory effect on CYP46A1 activity in vitro and in vivo, and the protein expressions of CYP46A1, HMGCR, and NMDAR are also inhibited by GP, which are of considerable clinical significance for GP's potential therapeutic role in treating neurological diseases.

In silico pharmacokinetic and therapeutic evaluation of Musa acuminata peels against aluminium chloride-induced hepatotoxicity in adult BALB/c mice.

East Africa (Musa spp.), notably Musa acuminata, "Matooke" a staple and economically important food in the region. Here, 12 selected M. acuminata peels extract (MAPE) bioactive compounds were studied for hepatoprotective potentials in aluminium chloride-induced hepatoxicity in adult BALB/c mice. GC-MS analysis was used to identify active components of MAPE. In silico estimation of the pharmacokinetic, the GCMS-identified compounds' toxicity profile and molecular docking were compared with the standard (Simvastatin) drug. Hepatotoxicity was induced using aluminium-chloride treated with MAPE, followed by biochemical and histopathological examination. Twelve bioactive compounds 2,2-Dichloroacetophenone (72870), Cyclooctasiloxane 18993663), 7-Hydroxy-6,9a-dimethyl-3-methylene-decahydro-azuleno[4,5-b]furan-2,9-dione (534579), all-trans-alpha-Carotene (4369188), Cyclononasiloxane (53438479), 3-Chloro-5-(4-methoxyphenyl)-6,7a-dimethyl-5,6,7,7a-tetrahydro-4H-furo[2,3-c]pyridin-2-one (536708), Pivalic acid (6417), 10,13-Octadecadienoic acid (54284936), Ethyl Linoleate (5282184), Oleic acid (5363269), Tirucallol (101257), Obtusifoliol (65252) were identified by GC-MS. Of these, seven were successfully docked with the target proteins. The compounds possess drug likeness potentials that do not inhibits CYP450 isoforms biotransformation. All the docked compounds were chemoprotective to AMES toxicity, hERGI, hERGII and hepatotoxicity. The animal model reveals MAPE protective effect on liver marker's function while the histological studies show regeneration of the disoriented layers of bile ducts and ameliorate the cellular/histoarchitecture of the hepatic cells induced by AlCl3. The findings indicate that MAPE improved liver functions and ameliorated the hepatic cells' cellular or histoarchitecture induced by AlCl3. Further studies are necessary to elucidate the mechanism action and toxicological evaluation of MAPE's chronic or intermittent use to ascertain its safety in whole organism systems.

Rapid chemical characterization and pharmacological mechanism of Fining Granules in the treatment of chronic bronchitis based on UHPLC–Q-exactive orbitrap mass spectrometer and network pharmacology

BackgroundSenecio cannabifolius Less. is a perennial herb belonging to the Compositae family that has been used in traditional medicine as an antitussive and expectorant for treating chronic bronchitis and acute respiratory infections. Traditionally, Feining Granules are prepared from water extracts of the raw plant material. However, the chemical composition and pharmacological mechanisms of Feining Granules have not been thoroughly investigated. MethodsA systematic strategy for the rapid detection and identification of the constituents of Feining Granules was developed using ultrahigh-performance liquid chromatography–quadrupole-exactive orbitrap mass spectrometry (MS) with parallel reaction monitoring. ResultsOverall, 162 compounds, including flavonoids, alkaloids, organic acids, and others, were identified unambiguously and tentatively by comparing the retention times and MS fragmentation with reference standards and literature data. Ninety-nine of these were reported for the first time to the best of our knowledge. Network pharmacology suggests that Feining Granules can be used to treat chronic bronchitis as they contain active components associated with the ALB, VEGFA, and SRC target genes influenced by HIF-1, VEGF, and other signaling pathways. ConclusionThese results provide information that can help understand the effective substances of S. cannabifolius Less. and improve quality control.

Rare Earth Chlorides in Low-Hydration Magnesium Chloride Electrolysis: Mechanistic Insights

Abstract During the molten salt electrolysis of magnesium production, water in the magnesium chloride (MgCl2) feedstock poses significant interference, reducing the current efficiency. Employing rare earth chlorides (RECl3) to assist in dehydrating magnesium chloride and producing Mg-RE master alloys emerges as an effective strategy. This study investigated the transformation process in the hydrolysis reaction of low-hydrate MgCl2 within the molten salt, examining the electrochemical activity of its hydrolysis products using Cyclic voltammetry (CV). Additionally, a thermodynamic analysis of the reaction between hydrolyzate MgO and RECl3 was performed at electrolysis temperatures. By integrating CV and Square wave voltammetry (SWV) with X-ray diffraction (XRD) analysis, the study explored the alterations in the electrochemically active components of the molten salt system following the addition of RECl3 to the KCl-NaCl molten salt containing MgO.

Exploring the pharmacognostical and phytochemical profiles of aqueous extracts of Kalanchoe.

The use of plants for medicinal purposes has a long history, however it is desirable a continuous evaluation seeking for complementary scientific evidences for their safe application. Species within the Kalanchoe genus are often referred to as "miracle leaf" due to their remarkable healing properties. Traditionally, these plants have been used to treat infections, inflammation, and cancer. Despite their widespread use, the identification of their active components remains incomplete. This study aimed to differentiate K. crenata (KC), K. marmorata (KM), and K. pinnata (KP) by conducting detailed histochemical and phytochemical analyses, and to assess their antioxidant capabilities. The investigation revealed significant differences between the species, highlighting the variability in phenolic (PC) and flavonoid contents (FC) and their distinct antioxidant effects. The KM demonstrated the greatest results (PC: 59.26 ± 1.53 mgEqGA/g; FC: 12.63 ± 0.91 mgEqCQ/g; DPPH• (IC50): 110.66 ug/ml; ABTS•+ (IC50): 26.81 ug/ml; ORAC: 9.65 ± 0.75 mmolTE) when compared to KC and KP. These findings underscore a new reference for research within the Kalanchoe genus.

ChEdBot: Designing a Domain-Specific Conversational Agent in a Simulational Learning Environment Using LLMs

We propose conversational agents as a means to simulate expert interviews, integrated into a simulational learning environment: ChEdventure. Designing and developing conversational agents using the existing tools and frameworks requires technical knowledge and a considerable learning curve. Recently, LLMs are being leveraged for their adaptability to different domains and their ability to perform various tasks in a natural, human-like conversational style. In this work, we explore if LLMs can help educators easily create conversational agents for their individual teaching goals. We propose a generalized template-based approach using LLMs that can instantiate conversational agents as an integrable component of teaching and learning activities. We evaluate our approach using prototypes generated from this template and identify guidelines to improve the experience of educators.

Colloid phase separation dynamics driven by chiral turbulent flows

Hydrodynamic interactions significantly influence phase-ordering kinetics in complex fluids. While passive fluid phase separation is well studied, the impact of active components remains relatively unexplored. We examine pure- and quasi-two-dimensional mixtures of attractive colloids and self-rotating particles in a solvent. Varying rotor rotational speed and area fraction yield diverse dynamic patterns such as percolated networks and round droplets composed of passive colloids alone. At intermediate rotation speeds, inertial chiral flows, accompanied by the inverse energy cascade, lead to self-similar power-law coarsening with a growth exponent of 1/2. The flows spontaneously organize within fluid domains, exhibiting turbulent and chiral characteristics. Surprisingly, these turbulent flows can sustain hexatic order hydrodynamically stabilized by the Magnus force under certain conditions. Conversely, at higher speeds, nonlinear hydrodynamic interactions impede phase separation. Our findings illuminate the intriguing dynamic interplay between phase separation and chiral turbulence, effectively bridging the realms of phase ordering and turbulent physics.

Application of a new brine of sprouted grains for delicatessen products from horse meat, beef, and pork

The main task of the meat processing industry is to produce meat products as the primary source of animal protein that ensures the vital activity of the human body in the necessary volumes, high quality, and a diverse assortment. Providing the population with high-quality food products that are biologically complete, balanced in the composition of the primary nutrients, and enriched with target physiologically active components is one of the most priority scientific and technical problems to be solved. In this regard, a recipe for a new brine from sprouted grains for delicatessen products from horse meat, beef, and pork was developed. The composition of the new brine includes flavoring and aromatic ingredients, juice of sprouted grains, and juices of raw vegetable materials. The viscosity of horse meat, beef, and pork during massaging was studied. Thermodynamic parameters such as water activity and moisture binding energy of horse meat, beef, and pork using a new brine were studied. The data analysis shows that the values of the “aw” indicator and the moisture binding energy in the experimental samples of meat products are higher than in the control samples. Studies have found that with an increase in the activity of water and the moisture binding energy, the tenderness of finished delicatessen meat products with a new brine increases. As a result, it was found that the maximum amount of brine in horse meat is retained at 160 minutes of continuous massaging, in beef – at 130 minutes, in pork – at 120 minutes of mechanical processing.

A generalist regulator: MYB transcription factors regulate active ingredient biosynthesis in medicinal plants.

Medicinal plants are rich in a variety of secondary metabolites with therapeutic value. However, the yields of these metabolites are generally very low, making their extraction both time- and labour-consuming. Transcription factor (TF)-targeted secondary metabolic engineering can efficiently regulate the biosynthesis and accumulation of secondary metabolites in medicinal plants. v-Myb avian myeloblastosis viral oncogene homolog (MYB) TFs are involved in regulating various morphological and developmental processes, responses to stress, and the biosynthesis of secondary metabolites in plants. This review discusses the biological functions and transcription regulation mechanisms of MYB TFs and summarises the research progress concerning MYB TFs involved in the biosynthesis of representative active components. In the transcriptional regulatory network, MYB TFs regulate multiple synthase genes to mediate active ingredient biosynthesis. This study will serve as a reference for the in-depth analysis of the MYB TF family in medicinal plants.

The Preparation and Contact Drying Performance of Encapsulated Microspherical Composite Sorbents Based on Fly Ash Cenospheres.

Sorption technologies are essential for various industries because they provide product quality and process efficiency. New encapsulated microspherical composite sorbents have been developed for resource-saving contact drying of thermolabile materials, particularly grain and seeds of crops. Magnesium sulfate, known for its high water capacity, fast sorption kinetics, and easy regeneration, was used as an active moisture sorption component. To localize the active component, porous carriers with an accessible internal volume and a perforated glass-crystalline shell were used. These carriers were created by acid etching of cenospheres with different structures isolated from fly ash. The amount of magnesium sulfate included in the internal volume of the microspherical carrier was 38 wt % for cenospheres with ring structures and 26 wt % for cenospheres with network structures. Studies of the moisture sorption properties of composite sorbents on wheat seeds have shown that after 4 h of contact drying the moisture content of wheat decreases from 22.5 to 14.9-15.5 wt %. Wheat seed germination after sorption drying was 95 ± 2%. The advantage of composite sorbents is the encapsulation of the desiccant in the inner volume of perforated cenospheres, which prevents its entrainment and contamination and provides easy separation and stable sorption capacity in several cycles.

A novel compounded cyproheptadine hydrochloride oral solution: Accelerated stability study and effects on glucose and lipid metabolism in Wistar rats

The present study developed a compounded oral solution (COS) containing an active component cyproheptadine hydrochloride (CY) in association with pharmaceutical adjuvants. The main objective is to demonstrate the stability of this solution and the in vivo effects on serum and liver parameters of glucose and lipid metabolism. After 180 days of analysis the COS showed physicochemical stability (pH and specific gravity) when submitted to different temperatures (24 °C and 40 °C), but the chemical stability, presented by the content of CY (%) in the formulation, showed that the degradation rate of CY increased 20x when submitted to a stress condition (40 °C). Male Wistar rats were treated with IOS 1.5 (industrial oral solution 1.5 mg.kg-1) or saline for 21 days and IOS 5.0 or COS (5 mg.kg-1) or placebo by gavage for 23 days. Treatment with IOS 1.5 increased liver cholesterol by 30 % without changing liver and body weight in this group. In contrast, treatment with IOS and COS (5 mg.kg-1) increased final body weight by 8 % compared to placebo. Interestingly, the COS group had increased liver glycogen accompanied by reduced food intake compared to IOS. However, COS and IOS 5.0 did not induce changes in adipose tissue weight, liver weight, as well as serum glucose, triacylglycerol and cholesterol levels. This work provides us with data that prove the stability of the compound solution at room temperature, as well as inducing an increase in the final body weight of rats with no alteration in glucose and lipid metabolism.

Investigating the molecular mechanism of Mori Cortex against osteosarcoma by bioinformatics analysis and in vitro experimental.

To explore the therapeutic mechanism of Mori Cortex against osteosarcoma (OS), we conducted bioinformatics prediction followed by in vitro experimental validation. Gene expression data from normal and OS tissues were obtained from the GEO database and underwent differential analysis. Active Mori Cortex components and target genes were extracted from the Traditional Chinese Medicine System Pharmacology database. By intersecting these targets with differentially expressed genes in OS, we identified potential drug action targets. Using the STRING database, a protein-protein interaction network was constructed. Subsequent analyses of these intersected genes, including Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment, were performed using R software to elucidate biological processes, molecular functions, and cellular components, resulting in the simulation of signaling pathways. Molecular docking assessed the binding capacity of small molecules to signaling pathway targets. In vitro validations were conducted on U-2 OS cells. The CCK8 assay was used to determine drug-induced cytotoxicity in OS cells, and Western Blotting was employed to validate the expression of AKT, extracellular signal-regulated kinases (ERK), Survivin, and Cyclin D1 proteins. Through differential gene expression analysis between normal and OS tissues, we identified 12,364 differentially expressed genes. From the TCSMP database, 39 active components and 185 therapeutic targets related to OS were derived. The protein-protein interaction network indicated that AKT1, IL-6, JUN, VEGFA, and CASP3 might be central targets of Mori Cortex for OS. Molecular docking revealed that the active compound Morusin in Mori Cortex exhibits strong binding affinity to AKT and ERK. The CCK8 assay showed that Morusin significantly inhibits the viability of U-2 OS cells. Western Blot demonstrated a reduction in the p-AKT/AKT ratio, the p-ERK/ERK ratio, Survivin, and Cyclin D1. Mori Cortex may exert its therapeutic effects on OS through multiple cellular signaling pathways. Morusin, the active component of Mori Cortex, can inhibit cell cycle regulation and promote cell death in OS cells by targeting AKT/ERK pathway.

Monte Carlo study of magnetic properties of the fullerene C24 structure

ABSTRACT The fullerene C24 is one of the most active types of nanostructures and has been used as an active component in important applications. In this study, we investigated the magnetic characteristics of the mixed spins 5/2 and 3/2 of the Fullerene C24 system using Monte Carlo simulations. We start by offering a theoretical analysis of ground state phase diagrams. In fact, out of all potential configurations, we only present and analyze the stable configurations. Secondly, calculations are done to determine how the magnetic characteristics of this compound change as various physical parameters are changed. Additionally, we offer the examined magnetic behavior of the system with reduced temperature, reduced crystal field, reduced exchange-coupling interactions, and reduced external magnetic field. Finally, we looked into and talked about the critical reduced temperature of Fullerene C24. We showed and examined the hysteresis loops for various physical parameter values to end our work.
