With the growing understanding of osteoporosis, increasing literature has highlighted the regulatory role of m6A methylation in this condition. However, there is currently no reliable method to stably regulate cellular m6A methylation levels. Here, we report a novel approach utilizing alendronate (aln)-modified mesoporous silica nanoparticles (MSNs) to deliver sodium bicarbonate and piR7472, modulating cellular behavior. Our experimental results demonstrate that Aln modification enables the nanoparticles to stably target hydroxyapatite, thereby accumulating in osteoporotic regions. Sodium bicarbonate suppresses osteoclastogenesis, while piR7472 enhances m6A methylation, promoting osteogenic differentiation of bone marrow stromal cells (BMSCs). Computed tomography (CT) and hematoxylin and eosin (HE) staining showed that after 2 weeks of treatment with MSNs-Na@piR7472, cortical bone thickened, trabecular bone density increased, collagen fiber thickness improved, and both the number and staining area of osteoclasts were significantly reduced. These findings indicate a marked improvement in osteoporosis.</div></div>","PeriodicalId":249,"journal":{"name":"Arabian Journal of Chemistry","volume":"17 12","pages":"Article 106040"},"PeriodicalIF":5.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we fabricated microcavity patterned silicon surfaces, and quantitatively explored the amount and distribution of Escherichia coli (<em>E. coli</em>) cells attached on a series of defined topographies. The results showed that <em>E. coli</em> cells enrichment was significantly increased on silicon nanowires-based microcavity array when compared to nanowires patterned silicon wafer. Furthermore, the microcavity diameter can control bacterial distribution by changing hydrophilic performance of interface. With the microcavity diameter of 7 µm, the cells colonized into the microcavity almost in its entirety, whilst distributed around the microcavity completely with 10 µm diameter, regardless of centre distances. This phenomenon can be explained by the Cassie-Baxter model equation according to the wettability. The distribution of bacterial enrichment changed with the silicon surfaces turning from non-wetting status to wetting status when treated with oxygen plasma to modify the hydrophobicity. These results demonstrated that microcavity patterned surface could favor bacterial enrichment on silicon and strictly confined bacterial distribution inside/outside the microcavity. Moreover, the nanowires inside microcavity can also increase electron conductivity and reduce the internal resistance, thus providing scientific evidence for the design of wearable microbial fuel cell with rational optimization and integration of different components for electronic skin.</div></div>","PeriodicalId":249,"journal":{"name":"Arabian Journal of Chemistry","volume":"17 12","pages":"Article 106013"},"PeriodicalIF":5.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve strong antibacterial activity, it is necessary to improve the enzyme-like activity of MOFs. In this study, Fe_xCoMOF was synthesized by incorporating Co(II) to improve the electron transfer of Fe(III)/Fe(II), which enhanced its redox capacity as a nanozyme and further promoted the generation of hydroxyl radical (⋅OH), exhibiting higher POD activity. Doping with different amounts of Co(II) altered the particle size, specific surface area, and surface defects of Fe_xCoMOF, thus exhibiting differential enzyme-like activities. Additionally, a glucose-responsive enzyme cascade reaction system based on Fe₄CoMOF/glucose oxidase (GOx) was established. In the presence of glucose, the <em>in situ</em>-generated substrate H₂O₂ was in contact with the catalytic site and the generated gluconic acid enabled Fe₄CoMOF to maintain maximum enzyme activity under physiological pH conditions, avoiding damage caused by the use of exogenous high concentrations of H₂O₂. In the <em>in vitro</em> antibacterial experiment, the minimum inhibitory concentration (MIC) of Fe₄CoMOF/GOx was 10 μg mL⁻¹ for <em>Escherichia coli</em> (<em>E. coli</em>) and 5 μg mL⁻¹ for <em>Staphylococcus aureus</em> (<em>S. aureus</em>) (∼10⁸ CFU mL⁻¹). The increase in enzyme activity resulted in a considerable reduction in the dose of the antibacterial agent, which was conducive to improving bio-safety. The <em>in vivo</em> experiment in mice demonstrated that the glucose-responsive Fe₄CoMOF-based cascade reaction system had excellent antibacterial properties and remarkably promoted wound healing.

The etiology of epilepsy is varied and the neuroinflammation has been considered to be the prime initiator and the stimulator of the disease progression. Therefore anti-inflammatory drugs are suggested to treat seizure and also to prevent epilepsy. The currently available antiepileptic drugs cause’s adverse effects which obstructs the usage of these drugs and also these drugs are not cost effective. Phytochemicals are effective alternative to these drugs and it is prescribed in the traditional medicine. Conessine, a steroidal alkaloid present in bark extracts of Holarrhena sps possess antibiotic, anti-diarrheal, antimalarial and anti-inflammatory properties. We evaluated the antiepileptic potency of conessine in PTZ challenged animal model treated with 10 and 20 mg/kg of conessine respectively. The seizure induction, severity and the behavioral changes were observed in the rats. The impact of conessine on neurochemical signaling in PTZ challenged rats were assessed via quantifying the neurotransmitter and ATPase levels in the brain tissue. Antioxidants and MDA levels were measured to evaluate the antioxidant potency of conessine in epilepsy induced rats. iNOS and nNOS which are inducers of NO during epileptic conditions were analyzed in the test rats. The stimulators and inflammatory cytokines levels were quantified in the brain to analyze the anti-neuroinflammatory efficacy of the conessine in PTZ challenged rats. AKT/mTOR prime signaling proteins in initiation and progression of epilepsy was quantified in the brain tissue of experimental animals. Neurodegeneration inducers cytochrome <em>c</em>, NF-κB, COX-2 and Caspase 3 were quantified to evaluate the ameliorative potency of conessine against PTZ induced neuronal damage. The neuroprotective and antiepileptic potency of conessine was confirmed with the histopathological scoring of brain tissue in PTZ challenged rats. Conessine treatment effectively inhibited the seizure induction and regulated the neurochemical signaling in epileptic induced rats. It also attenuated the neuroinflammation and oxidative stress induction induced by PTZ treatment. The prime signaling proteins nitric oxide synthatase and AKT/mTOR signaling proteins were effectively inhibited by the conessine treatment which eventually prevented the neurodegeneration inducers. Conessine treatment significantly enhanced the levels of Caspase 3. The histopathological analysis confirms the neuroprotective, anti-inflammatory and antiepileptic potency of conessine. Conessine treatment also doesn’t caused any behavioral alterations in the rats hence it is safe and potent alternative for currently available antiepileptic drugs.</div></div>","PeriodicalId":249,"journal":{"name":"Arabian Journal of Chemistry","volume":"17 12","pages":"Article 106009"},"PeriodicalIF":5.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
