The clinical effect evaluation of multidisciplinary collaborative team combined with palliative care model in patients with terminal cancer: a randomised controlled study.

OBJECTIVE: To evaluate the clinical effect of a multidisciplinary collaboration team combined with a palliative care model in patients with terminal cancer. METHOD: A total of 84 patients diagnosed with terminal cancer in our hospital were included and randomly divided into an intervention group and a control group, with 42 cases in each group. Patients in the intervention group were treated by a multidisciplinary collaborative team combined with the palliative care model, and patients in the control group were treated by routine nursing intervention. The Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS) were used to evaluate negative emotions and anxiety and depression of patients before and after intervention. The Quality of Life Scale (European Organization for Research and Treatment of Cancer [EORTC] QLQ-C30) and Social Support Scale (SSRS) were used to evaluate the quality of life and social support of patients. This study has been registered in 13/01/2023 (ClinicalTrials.gov Identifier: NCT05683236). RESULT: The general data of the two groups were comparable. After intervention, the SAS (43.7 ± 7.4 vs. 54.2 ± 9.3) and SDS scores (38.4 ± 6.5 vs. 53.1 ± 8.4) of the intervention group were significantly lower than those of the control group. The total SSRS score, subjective support score, objective support score and utilisation of support of the intervention group were significantly higher than those of the control group (P < 0.05). The overall quality of life score of the intervention group was higher than that of the control group, and the difference was statistically significant (79.5 ± 4.5 vs. 73.2 ± 3.6, P < 0.05). The scores of each functional scale were significantly higher than those of the control group (P < 0.05). CONCLUSION: Compared with conventional nursing, the application of the multidisciplinary collaborative team combined with tranquilisation therapy in patients with terminal cancer can significantly reduce the anxiety and depression of patients, enable patients to obtain comprehensive social support, and effectively improve the quality of life of patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT05683236, 13/01/2023, Retrospectively registered.

Characterization of antimicrobial resistance and virulence genes of Pseudomonas aeruginosa isolated from mink in China, 2011-2020.

Pseudomonas aeruginosa strains are potential pathogens that cause respiratory diseases in minks, and caused serious economic loss to mink breeding industry. In this study, we identified antimicrobial resistance and virulence genes in 125 P. aeruginosa isolates from mink in China from 2011 to 2020. The results showed at least one mutation in the gyrA (Thr83Val or Asp87Gly) and parC (Ser87 Leu) genes as well as single mutations in 56 isolates. At least 4-fold reductions in the fluoroquinolone minimum inhibitory concentration values were found when tested in the presence of PAßN in 23 isolates, while 44 isolates were positive for the extended spectrum ß-lactamases and 15 antibiotic resistance genes were identified in this population with a prevalence between 1-32%, including qnrA, CTX-M-1G, ermB and C, cmlA, flor, catl, intl1, tetA, B, C, and D as well as sul1, 2, and 3 genes. Interestingly, one isolate carried ten resistance genes. Five virulence genes were detected, where exoS and algD were the most frequently detected (76.8%), which were followed by plcH (76%), lasB (73.6%), and pilB (31.2%). The isolates carrying the antibiotic resistance or virulence genes were genetically variable, suggesting a horizontal spread through the population. Hence, this study provides novel and important data on the resistance and pathogenicity of P. aeruginosa in farmed mink infections. These data provide important insights into the mechanism of fluoroquinolone resistance in P. aeruginosa, highlighting its usefulness in the treatment and control of P. aeruginosa infections in minks.

Antimicrobial Secondary Metabolites from the Seawater-Derived Fungus Aspergillus sydowii SW9.

Marine-derived fungi are considered to be valuable producers of bioactive secondary metabolites used as lead compounds with medicinal importance. In this study, chemical investigation of the seawater-derived fungus Aspergillus sydowii SW9 led to the isolation and identification of one new quinazolinone alkaloid, 2-(4-hydroxybenzyl)-4-(3-acetyl)quinazolin-one (1), one new aromatic bisabolene-type sesquiterpenoid, (2) and one new chorismic acid analogue (3), as well as two known alkaloids (compounds 4 and 5). Their structures were determined by extensive 1D/2D NMR and mass spectrometric data, and the absolute configurations of 2 and 3 were assigned by the analysis of ECD spectra aided by quantum chemical computations. Compounds 1, 2, and 4 exhibited selective inhibitory activities against the human pathogenic bacteria Escherichia coli, Staphylococcus aureus, S. epidermidis, and Streptococcus pneumoniae, with MIC values ranging from 2.0 to 16 µg/mL.

[Screening potential DNA barcode regions of genus Papaver].

DNA barcoding is an effective technique in species identification. To determine the candidate sequences which can be used as DNA barcode to identify in Papaver genus, five potential sequences (ITS, matK, psbA-trnH, rbcL, trnL-trnF) were screened. 69 sequences were downloaded from Genbank, including 21 ITS sequences, 10 matK sequences, 8 psbA-trnH sequences, 14 rbcL sequences and 16 trnL-trnF sequences. Mega 6.0 was used to analysis the comparison of sequences. By the methods of calculating the distances in intraspecific and interspecific divergences, evaluating DNA barcoding gap and constructing NJ and UPMGA phylogenetic trees. The sequence trnL-trnF performed best. In conclusion, trnL-trnF can be considered as a novel DNA barcode in Papaver genus, other four sequences can be as combination barcode for identification.

[Progress of experimental research on treating Alzheimer's disease by acupuncture].

To discuss the pathogenesis of Alzheimer's disease (AD), we summarized the mechanisms of treating AD animal models by acupuncture from literatures in recent years as follows. Senile dementia rats' cognitive capabilities and memory could be improved by reduction of beta-amyloid protein, attenuation of excessive phosphorylation of tau protein, regulation of center neurotransmitter dysmetabolism, oxidation of anti-free radicals, reduction of neuron apoptosis in the cortex and the hippocampus, inhibition of glial cells' differentiation, adjustment of G protein signaling transduction, and improvement of the mitochondrial dysfunction, thus providing experimental evidence for treating AD by acupuncture.

Metastatic clear cell sarcoma of the pancreas: A rare case report.

BACKGROUND: Clear cell sarcoma (CCS) is a rare soft-tissue sarcoma. The most common metastatic sites for CCS are the lungs, bones and brain. CCS is highly invasive and mainly metastasizes to the lung, followed by the bone and brain; however, pancreatic metastasis is relatively rare. CASE SUMMARY: We report on a rare case of CCS with pancreatic metastasis in a 47-year-old man. The patient had a relevant medical history 3 years ago, with abdominal pain as the main clinical manifestation. No abnormalities were observed on physical examination and the tumor was found on abdominal computed tomography. Based on the medical history and postoperative pathology, the patient was diagnosed with CCS with pancreatic metastasis. The patient was successfully treated with surgical interventions, including distal pancreatectomy and splenectomy. CONCLUSION: This report summarizes the available treatment modalities for CCS and the importance of regular postoperative follow-up for patients with CCS.

Anti-adipogenesis and anti-obesity potential of alliin mediated by modulating glycolipid metabolism via activating PPARγ signaling.

Garlic exhibits hypolipidemic, hypoglycemic, and cardiovascular benefits. The inconsistent results of garlic preparations on adipogenesis have caused more confusion in the public and academia. The compounds responsible for the anti-adipogenesis effect of garlic remain unknown. The present study aimed to verify the real anti-adipogenesis and anti-obesity component in garlic and explored its possible effects in metabolic syndrome. We verified the real anti-adipogenesis and anti-obesity components of garlic in 3T3-L1 preadipocytes and a 10-week-high fat diet (HFD)-induced obese mice. In vitro, two water-soluble and four typical lipid-soluble compounds of garlic were tested for their anti-adipogenesis. Then, the water-soluble compound, alliin, and two processing methods produced garlic oils, were evaluated in vivo study. Mice received oral administration of alliin (25 mg/kg) and garlic oils (15 mg/kg) daily for 8 weeks. Serum lipids, parameters of obesity, and indicators involved in regulating glycolipid metabolism were examined. Our findings confirmed that both water-soluble and lipid-soluble organosulfur compounds of garlic contributed to garlic's anti-adipogenesis effect, in which water-soluble sulfides, especially alliin, exhibited greater potency. Alliin possessed potent effects of anti-obesity and improvement in glucose and lipid metabolism in HFD-induced obese mice. Alliin mediated these effects partly attributed to its modulation of enzymatic activities within glycolipid metabolism and activating PPARγ signaling pathway. In contrast to odorous lipid-soluble sulfides, alliin is odorless, stable, and safe, and is an ideal nutraceutical or even medicinal candidates for the treatment of metabolic diseases. Alliin could be used to standardize the quality of garlic products.

IL-17A/p38 Signaling Pathway Induces Alveolar Epithelial Cell Pyroptosis and Hyperpermeability in Sepsis-Induced Acute Lung Injury by Activating NLRP3 Inflammasome.

Sepsis is a syndrome with poor prognosis. Nucleotide-binding domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome and T helper 17 (Th17) cells are involved in the pathogenesis of inflammatory diseases. This study aims to explore their roles and underlying mechanisms in sepsis. The blood and bronchoalveolar lavage fluid are collected from sepsis patients and healthy donors. A sepsis mice model is established by cecal ligation puncture (CLP). The contents of cytokines are detected by ELISA. The amounts of Th17 cells, IL-17A, IL-1ß, IL-18, and lipopolysaccharide is significantly elevated in sepsis patients. The increased differentiation of Th17 cells can promote lung cell pyroptosis and induce hyperpermeability via activating NLRP3 inflammasome and p38 pathway. The inhibitors targeting Th17 cells, NLRP3 inflammasome, and p38 pathway can significantly alleviate lung injury in sepsis mice. Th17 cells can secrete IL-17A to activate NLRP3 inflammasome via p38 signaling pathway, which contributes to the development of sepsis-induced acute lung injury.

The immunomodulation role of Th17 and Treg in renal transplantation.

Kidney transplantation (KT) is an ultimate treatment of end-stage chronic kidney disease, which can meet a lot of complications induced by immune system. With under-controlled immunosuppression, the patient will obtain a good prognosis. Otherwise, allograft disfunction will cause severe organ failure and even immune collapse. Acute or chronic allograft dysfunction after KT is related to Th17, Treg, and Th17/Treg to a certain extent. Elevated Th17 levels may lead to acute rejection or chronic allograft dysfunction. Treg mainly plays a protective role on allografts by regulating immune response. The imbalance of the two may further aggravate the balance of immune response and damage the allograft. Controlling Th17 level, improving Treg function and level, and adjusting Th17/Treg ratio may have positive effects on longer allograft survival and better prognosis of receptors.

Multi-Layered Branched Surface Fluorination on PVDF Membrane for Anti-Scaling Membrane Distillation.

Membrane distillation (MD) has emerged as a promising technology for hypersaline wastewater treatment. However, membrane scaling is still a critical issue for common hydrophobic MD membranes. Herein, we report a multi-layered surface modification strategy on the commercial polyvinylidene fluoride (PVDF) membrane via plasma treatment and surface fluorination cycles. The repeated plasma treatment process generates more reaction sites for the fluorination reaction, leading to higher fluorination density and more branched structures. MD tests with CaSO4 as the scaling agent show that the modification strategy mentioned above improves the membrane scaling resistance. Notably, the PVDF membrane treated with three cycles of plasma and fluorination treatments exhibits the best anti-scaling performance while maintaining almost the same membrane flux as the unmodified PVDF membrane. This study suggests that a highly branched surface molecular structure with low surface energy benefits the MD process in both membrane flux and scaling resistance. Besides, our research demonstrates a universal and facile approach for membrane treatment to improve membrane scaling resistance.

RNA-Seq profiling of circular RNAs in human colorectal cancer 5-fluorouracil resistance and potential biomarkers.

BACKGROUND: Colorectal cancer (CRC) is a commonly diagnosed cancer of the digestive system worldwide. Although chemotherapeutic agents and targeted therapeutic drugs are currently available for CRC treatment, drug resistance is a problem that cannot be ignored and needs to be solved. AIM: To explore the relationship between circular RNA (circRNA) and CRC drug resistance. circRNA plays a key role in the occurrence and development of cancers, but its function in the process of drug resistance has not been widely revealed. METHODS: To explore the role of circRNA in 5-fluorouracil (5-Fu) resistance, we performed the circRNA expression profile in two CRC cell lines and their homologous 5-Fu resistant cells by high-throughput sequencing. RESULTS: We validated the differentially expressed circRNAs in other two paired CRC cells, confirmed that circ_0002813 and circ_0000236 could have a potential competitive endogenous RNA mechanism and be involved in the formation of 5-Fu resistance. And we combined the sequencing results of mRNA to construct the regulatory network of circRNA-miRNA-mRNA. CONCLUSION: Our study revealed that circ_0002813 and circ_0000236 may as the biomarkers to predict the occurrence of 5-Fu resistance in CRC.

Preliminary Study on the Combination Effect of Clindamycin and Low Dose Trimethoprim-Sulfamethoxazole on Severe Pneumocystis Pneumonia After Renal Transplantation.

Objective: Evaluate the effect of the combination of clindamycin with low-dose trimethoprim-sulfamethoxazole (TMP/SMX) regimen on sever Pneumocystis pneumonia (PCP) after renal transplantation. Method: 20 severe PCP patients after renal transplantation were included in this historical-control, retrospective study. A 10 patients were treated with the standard dose of TMP/SMX (T group), the other 10 patients were treated with the combination of clindamycin and low dose TMP/SMX (CT group). Results: Although there was no significant difference in the hospital survival between the two groups, the CT protocol improved the PaO2/FiO2 ratio more significantly and rapidly after the 6th ICU day (1.51 vs. 0.38, P = 0.014). CT protocol also ameliorated the pulmonary infiltration and the lactate dehydrogenase level more effectively. Moreover, the CT protocol reduced the incidence of pneumomediastinum (0 vs. 50%, P = 0.008), the length of hospital staying (26.5 vs. 39.0 days, P = 0.011) and ICU staying (12.5 vs. 22.5 days, P = 0.008). Furthermore, more thrombocytopenia (9/10 vs. 3/10, P = 0.020) was emerged in the T group than in the CT group. The total adverse reaction rate was much lower in the CT group than in the T group (8/80 vs. 27/80, P < 0.001). Consequently, the dosage of TMP/SMX was reduced in 8 patients, while only 2 patients in the CT group received TMP/SMX decrement (P = 0.023). Conclusion: The current study proposed that clindamycin combined with low-dose TMP/SMX was more effective and safer the than single use of TMP/SMX for severe PCP patients after renal transplantation (NCT04328688).

Identification of the major photodegradant in metronidazole by LC-PDA-MS and its reveal in compendial methods.

Metronidazole in aqueous solution is sensitive to light and UV irradiation, leading to the formation of N-(2-hydroxyethyl)-5-methyl-l,2,4-oxadiazole-3-carboxamide. This is revealed here by liquid chromatography with tandem photo diode array detection and mass spectrometry (LC-PDA-MS) and further verified by comparison with the corresponding reference substance and proton nuclear magnetic resonance (1H-NMR). However, in current compendial tests for related substances/organic impurities of metronidazole, the above photolytic degradant could not be detected. Thus, when photodegradation of metronidazole occurs, it could not be demonstrated. In our study, an improved LC method was developed and validated, which includes a detection at a wavelength of 230 nm and optimization of mobile phase composition thereby a better separation was obtained.

Macrophages play a role in inflammatory transformation of colorectal cancer.

Colorectal cancer (CRC) is one of the most common and fatal cancers worldwide, and it is also a typical inflammatory cancer. The function of macrophages is very important in the tissue immune microenvironment during inflammatory and carcinogenic transformation. Here, we evaluated the function and mechanism of macrophages in intestinal physiology and in different pathological stages. Furthermore, the role of macrophages in the immune microenvironment of CRC and the influence of the intestinal population and hypoxic environment on macrophage function are summarized. In addition, in the era of tumor immunotherapy, CRC currently has a limited response rate to immune checkpoint inhibitors, and we summarize potential therapeutic strategies for targeting tumor-associated macrophages.

CircRNA_0084927 promotes colorectal cancer progression by regulating miRNA-20b-3p/glutathione S-transferase mu 5 axis.

BACKGROUND: Colorectal cancer (CRC) is the third most common cancer and the second most common cause of cancer-related death worldwide. The 5-year survival rate of patients with early-stage CRC could reach 90%, but it is very low in patients with advanced-stage CRC. Recent studies have shown that circular RNAs play important roles in regulating the migration and invasion of CRC cells. AIM: To elucidate the role of circRNA_0084927 (circ_0084927) in the migration and invasion of CRC cells and its underlying mechanism. METHODS: Clinical tissue samples and cells were collected, and the expression of circ_0084927 was detected by quantitative polymerase chain reaction (qPCR). The diagnostic performance of circ_0084927 was assessed by receiver operating characteristic curve analysis. The role of circ_0084927 in CRC cell proliferation, migration, and invasion was determined using cell counting kit-8 assay, wound healing assay, and transwell assay, respectively. The regulatory relationship among circ_0084927, miRNA-20b-3p (miR-20b-3p), and glutathione S-transferase mu 5 (GSTM5) was identified using databases, luciferase reporter assay, qPCR, and Western blot analysis. AKT-mTOR signaling was also verified after circ_0084927 knockdown or miR-20b-3p mimic treatment. RESULTS: The expression of circ_0084927 was significantly increased in CRC tissues and cells, and it was higher in advanced-stage CRC compared with early-stage CRC. The area under the curve (AUC) of circ_0084927 was 0.806 [95% confidence interval (CI): 0.683-0.896]. In addition, the AUC was 0.874 (95%CI: 0.738-0.956) in patients with advanced-stage CRC and 0.713 (95%CI: 0.555-0.840) in those with early-stage CRC. Knockdown of circ_0084927 inhibited the migration and invasion of HCT116 cells. Moreover, circ_0084927 was found to act as a sponge of miR-20b-3p. MiR-20b-3p activation reduced the circ_0084927 level, whereas miR-20b-3p inhibition increased the circ_0084927 level. But the effect was not found after circ_0084927 mutation. In addition, miR-20b-3p expression in CRC patients was also reduced and negatively correlated with circ_0084927 expression. The function of circ_0084927 in HCT116 cells with circ_0084927 knockdown was rescued by miR-20b-3p. Moreover, GSTM5 expression was significantly decreased after overexpressing miR-20b-3p or inhibiting circ_0084927, but its expression was rescued when circ_0084927 and miR-20b-3p were both inhibited. Finally, AKT-mTOR signaling was markedly regulated by circ_0084927 and miR-20b-3p. CONCLUSION: The expression of circ_0084927 is significantly increased in CRC and higher in advanced-stage CRC than in early-stage CRC. Moreover, circ_0084927 potentially regulates CRC cell migration and invasion via the miR-20b-3p/GSTM5/ AKT/mTOR pathway.

[Abnormal expression of microRNAs in the hippocampus of Ts65Dn mice].

OBJECTIVE: To identify the differentially expressed microRNAs in the hippocampus of Down Syndrome model mouse Ts65Dn. METHODS: Low molecular weight RNA from hippocampus were tailed and reverse transcribed by extended RT-primer. MicroRNAs primers were arrayed on plates according to the Tm of each primer. PCR were carried out at different annealing temperatures using a gradient real-time PCR instrument. The relative expression level of each microRNAs was calculated using the most stable reference gene as normalizer which was selected by geNorm and Normfinder software. RESULTS: miR-27a was identified as the most stable reference gene by geNorm and Normfinder software. Among the 52 microRNAs detected by real-time PCR array, miR-33 and miR-19a were significantly down-regulated, whereas miR-130 were significantly up-regulated in the hippocampus of Ts65Dn mice as compared with the euploid control mice. The expression of miR-802, which was the trisomy chromosome 16 derived microRNAs, was very low in hippocampus with no difference between the two groups. CONCLUSION: MicroRNAs are dysregulated in the hippocampus of Ts65Dn mice, which may contribute to the reduced neurogenesis of Down syndrome.

[Profiling of microRNAs in mouse brain with real-time PCR array].

OBJECTIVE: To examine global expression levels of microRNAs(miRNAs) in mouse cerebrum and to provide an important basis for detailed studies of individual miRNAs, their target genes, the miRNA-related regulatory networks in the mammalian central nervous system, and their implications in diseases. METHODS: Low molecular weight RNA from cerebrum of five C57BL/6J mice were tailed and reverse transcribed by extended RT-primer. miRNA primers were carefully designed and arrayed on plates according to the Tm of each primer. PCR was carried out at different annealing temperatures using a gradient real-time PCR instrument. The relative expression level of each miRNA was calculated using 5sRNA for normalization. RESULTS: Among the 285 miRNAs detected, 260 were positive with varying abundance. Their frequency distribution was approximately a normal distribution. The expression levels of most miRNAs were in accordance with previously published results by microarray. However, the positive rate was higher than that detected by microarray. miRNAs originating from the same hairpin precursors expressed at similar or significantly different levels. Clusters of proximal miRNAs were similar or quite different in abundance. It is suggested that the fate of miRNA after transcription determined their abundance. CONCLUSION: Using the RNA-tailing and primer-extension PCR array method, we obtained expression profile of miRNA in mouse cerebrum, especially the relative expression data of many low abundant miRNA in mouse cerebrum, which will be of special help for studying the fine-tuning function of low-level miRNAs.

Increasing specificity of real time PCR to detect microRNA through primer design and annealing temperature increase.

OBJECTIVE: To investigate the non-specific and inaccurate amplification in cases of highly similar sequences among family members and the length heterogeneity of mature microRNA (miRNA), and find a condition that discriminates maximally among similar miRNA family members and detects the accurate expression level of miRNAs. METHODS: Primers with their mismatches and/or 3' end at different positions were designed. Amplification efficiencies were compared using matched and various mismatched primers by RNA-tailing and primer-extension RT-PCR at different annealing temperatures. Expression levels of several miRNAs in mouse brain were compared using miRNA specific primers with different termini. RESULTS: Raising annealing temperatures 12 degrees Celsius-14 degrees Celsius above the T(m) of the primers maximally increased amplification specificity without sacrificing sensitivity. Primers designed with their termini on or near variant positions could efficiently discriminate between miRNA isoforms. Using primers that terminated before the end of the mature miRNA did not miss the detection of shorter mature miRNA and provided accurate expression levels. CONCLUSION: Careful primer design and higher annealing temperature can increase specificity and accuracy of real time PCR miRNA detection.

Resemblance in Corrosion Behavior of Selective Laser Melted and Traditional Monolithic ß Ti-24Nb-4Zr-8Sn Alloy.

Distinct corrosion behavior was reported in multiphased titanium alloys prepared by additive manufacturing and by traditional technologies because of different phase constituents formed during processing. An open question is therefore raised: is there always different corrosion behavior of materials prepared by different methods? This work reports resemble corrosion behavior of selective laser melted and wrought single ß-phase Ti-24Nb-4Zr-8Sn (Ti2448) in both NaCl solution and Hank's solution. The electrochemical measurements showed that both samples have close calculated polarization resistance and corrosion potential in NaCl solution, i.e., 4.99 ± 0.63 MΩ cm2 and -0.26 ± 0.01 V for the selective laser-melted Ti2448, and 4.42 ± 0.71 MΩ cm2 and -0.25 ± 0.01 V for the wrought Ti2448, respectively. Both samples reveal the same variation in weight change after 180-day immersion test in Hank's solution. Such resemblance in corrosion behavior without pitting morphologies is attributed to the formation of monolithic ß-phase during processing, which demonstrates that titanium alloys with single phase show comparable corrosion behavior regardless of the manufacturing methods adopted.

Compelling Rejuvenated Catalytic Performance in Metallic Glasses.

Metallic glasses (MGs) with the metastable nature and random atomic packing structure have attracted large attention in the catalytic family due to their superior catalytic performance. In contrast, their crystalline counterparts are restricted by the highly ordered packing structure, fewer surface active sites, and crystallographic defects for catalytic activity. The uncertainty of the different catalytic mechanisms and the intrinsic characteristics correlated to MGs and their crystalline counterparts become a major impediment to promote their catalytic efficiencies and widespread applications. Herein, it is reported that the excellent catalytic behavior in Fe-based MGs goes through a detrimental effect with the partial crystallization, but receives a compelling rejuvenation in the full crystallization. Further investigation reveals that multiphase intermetallics with electric potential differences in fully crystallized alloys facilitate the formation of galvanic cells. More importantly, extensively reduced grain boundaries due to grain growth greatly weaken electron trapping and promote inner electron transportation. The relatively homogenous grain-boundary corrosion in the intermetallics contributes to well-separated phases after reaction, leading to refreshment of the surface active sites, thereby quickly activating hydrogen peroxide and rapidly degrading organic pollutants. The exploration of catalytic mechanisms in the crystalline counterparts of MGs provides significant insights into revolutionize novel catalysts.
