Abstract
Spinal Cord Injury (SCI), one of the major factors of disability, can cause irreversible motor and sensory impairment. There are no effective therapeutic drugs and technologies available in domestic or foreign countries currently. Neural stem cells (NSCs), with the potential for multidirectional differentiation, are a potential treatment for SCI. However, it has been demonstrated that NSCs primarily differentiated into astrocytes rather than neurons due to the inflammatory microenvironment, and the current challenge remains to direct the differentiation of NSCs into neurons in the lesion site. It was reported that the microtubule-stabilizing agent paclitaxel (PTX) was able to promote the differentiation of NSCs into neurons rather than astrocytes after SCI. SDF-1α can recruit NSCs and thus guide the migration of stem cells. In this study, we developed a functional collagen scaffold by loading SDF-1α and nanoparticle-encapsulated PLGA-PTX into a 3D collagen porous scaffold, allowing for slow release of PTX. When the functional scaffolds were implanted into the injury site, it provided a neural regeneration conduit channel for the migration of NSCs and neuronal differentiation. Neural regeneration promoted the recovery of motor function and reduced glial scar formation after SCI. In conclusion, a 3D collagen porous scaffold combined with PLGA-PTX and SDF-1α is a promising therapeutic strategy for SCI repair.

Targeted Delivery of Anticancer Drug Loaded Charged PLGA Polymeric Nanoparticles Using Electrostatic Field. Macromol Biosci 2023; 23:e2300181. [PMID: 37399543 DOI: 10.1002/mabi.202300181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 06/10/2023] [Accepted: 06/28/2023] [Indexed: 07/05/2023]
Abstract
Pure positive electrostatic charges (PPECs) show suppressive effect on the proliferation and metabolism of invasive cancer cells without affecting normal tissues. PPECs are used for the delivery of drug-loaded polymeric nanoparticles (DLNs) capped with negatively charged poly(lactide-co-glycolide) (PLGA) and Poly(vinyl-alcohol) PVA into the tumor site of mouse models. The charged patch is installed on top of the skin in the mouse models' tumor region, and the controlled selective release of the drug is assayed by biochemical, radiological, and histological experiments on both tumorized models and normal rats' livers. It is found that DLNs synthesized by PLGA show great attraction to PPECs due to their stable negative charges, which would not degrade immediately in blood. The burst and drug release after less than 48h of this synthesized DLNs are 10% and 50%, respectively. These compounds can deliver the loaded-drug into the tumor site with the assistance of PPECs, and the targeted-retarded release will take place. Hence, local therapy can be achieved with much lower drug concentration (conventional chemotherapy [2 mg kg-1 ] versus DLNs-based chemotherapy [0.75 mg kg-1 ]) with negligible side effects in non-targeted organs. PPECs have many potential clinical applications for advanced-targeted chemotherapy with the lowest discernible side effects.

Abstract
Cancer is the leading cause of death after cardiovascular disease. Despite significant advances in cancer research over the past few decades, it is almost impossible to cure end-stage cancer patients and bring them to remission. Adverse effects of chemotherapy are mainly caused by the accumulation of chemotherapeutic agents in normal tissues, and drug resistance hinders the potential therapeutic effects and curing of this disease. New drug formulations need to be developed to overcome these problems and increase the therapeutic index of chemotherapeutics. As a chemotherapeutic delivery platform, three-dimensional (3D) scaffolds are an up-and-coming option because they can respond to biological factors, modify their properties accordingly, and promote site-specific chemotherapeutic deliveries in a sustainable and controlled release manner. This review paper focuses on the features and applications of the variety of 3D scaffold-based nano-delivery systems that could be used to improve local cancer therapy by selectively delivering chemotherapeutics to the target sites in future.

J Pers Med 2022; 12:jpm12081324. [PMID: 36013273 PMCID: PMC9410527 DOI: 10.3390/jpm12081324] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 08/01/2022] [Accepted: 08/14/2022] [Indexed: 11/30/2022] Open
Abstract
Nanotechnology, the art of engineering structures on a molecular level, offers the opportunity to implement new strategies for the diagnosis and management of pregnancy-related disorders. This review aims to summarize the current state of nanotechnology in obstetrics and cancer in pregnancy, focusing on existing and potential applications, and provides insights on safety and future directions. A systematic and comprehensive literature assessment was performed, querying the following databases: PubMed/Medline, Scopus, and Endbase. The databases were searched from their inception to 22 March 2022. Five independent reviewers screened the items and extracted those which were more pertinent within the scope of this review. Although nanotechnology has been on the bench for many years, most of the studies in obstetrics are preclinical. Ongoing research spans from the development of diagnostic tools, including optimized strategies to selectively confine contrast agents in the maternal bloodstream and approaches to improve diagnostics tests to be used in obstetrics, to the synthesis of innovative delivery nanosystems for therapeutic interventions. Using nanotechnology to achieve spatial and temporal control over the delivery of therapeutic agents (e.g., commonly used drugs, more recently defined formulations, or gene therapy-based approaches) offers significant advantages, including the possibility to target specific cells/tissues of interest (e.g., the maternal bloodstream, uterus wall, or fetal compartment). This characteristic of nanotechnology-driven therapy reduces side effects and the amount of therapeutic agent used. However, nanotoxicology appears to be a significant obstacle to adopting these technologies in clinical therapeutic praxis. Further research is needed in order to improve these techniques, as they have tremendous potential to improve the accuracy of the tests applied in clinical praxis. This review showed the increasing interest in nanotechnology applications in obstetrics disorders and pregnancy-related pathologies to improve the diagnostic algorithms, monitor pregnancy-related diseases, and implement new treatment strategies.

Abstract
AbstractNanoscale devices offer a lot of potential in drug delivery because of their small size. The goal of this work was to increase the oral bioavailability of the anti-cancer hydrophilic drug as 5-fluorouracil (5-FU) by incorporating it into poly (D, L-lactide-co-glycolide) nanoparticles (PLGNPs) using the double emulsion process, 5-FU- PLGNPs nanoparticles were created. Various factors, such as drug, polymer, and stabilizer concentrations, were investigated for assembly in order to arrive at the most effective formulation of 5-FU-PLGNPs. PLGNPs had a drug encapsulation efficiency of 9.75 to 24.8%. The prepared nanoparticles had a spherical shape and an average size of 212.3–285 nm, as shown by TEM. The dispersion of the drug into the prepared PLGNPs was confirmed by XRPD and FTIR. The optimized nanoparticles (F225) had high encapsulation efficiency 24.8 ± 0.21%, low particles size 212.3 ± 48.2 nm with an appropriate PDI value of 0.448, and ZP of − 48.3 ± 2.7 mV. The molecular dispersion of the medication within the system was validated by thermal behavior studies (DSC). In vitro drug release from the best-selected formulations revealed a sustained release of nanoparticles, with slower release reported when lower PVA concentrations were utilized. Three 5-FU-PLGNPs formulations were tested for anticancer efficacy against cell cultures of HCT-116 (human colorectal carcinoma), MCF-7 (human breast carcinoma), and HepG2 (human hepatocellular carcinoma). The created formulations were examined for in vitro cytotoxic activity, revealing that they appeared to be promising effective anticancer formulations when compared to the positive controlled (doxorubicin).

Abstract
Corona virus disease-2019 (COVID-19) emerged in Wuhan, China in December 2019 and was declared as a pandemic by the World Health Organization in March 2020. Although there is no complete treatment protocol for COVID-19, studies on this topic are ongoing, and it is known that broad-spectrum antibiotics such as cephalosporins are used for coinfections and symptoms in COVID-19 patients. Studies have shown that Staphylococcus aureus and Escherichia coli bacteria can cause symptoms such as diarrhea and coinfections accompanying COVID-19. Therefore, in this study, colon-targeted cefaclor monohydrate (CEF)-loaded poly(lactic-co-glycolic acid) (PLGA)-Eudragit S100 nanoparticles (NPs) were prepared using a nanoprecipitation technique. The particle sizes of the CEF-loaded NPs were between 171.4 and 198.8 nm. The encapsulation efficiency was in the range of 58.4%-81.2%. With dissolution studies, it has been concluded that formulations prepared with Eudragit S100 (E-coded) and Eudragit S100+PLGA (EP-coded) are pH-sensitive formulations and they are targetable to the colon, whereas the formulation prepared only with PLGA (P-coded) can release a higher CEF rate in the colon owing to the slow release properties of PLGA. The release kinetics were fitted to the Korsmeyer-Peppas and Weibull models. The antibacterial activity of E-, EP-, and P-coded formulations was 16-fold, 16-fold, and 2-fold higher than CEF, respectively, for S. aureus and E. coli according to the microdilution results. As a result of the time killing experiment, all formulations prepared were found to be more effective than the antibiotic itself for long periods. Consequently, all formulations prepared in this study hope to guide researchers/clinicians in treating both gram-positive and gram-negative bacteria-induced infections, as well as COVID-19 associated coinfections and symptoms.

Abstract
Molecular signaling pathways involved in cancer have been intensively studied due to their crucial role in cancer cell growth and dissemination. Among them, zinc finger E-box binding homeobox-1 (ZEB1) and -2 (ZEB2) are molecules that play vital roles in signaling pathways to ensure the survival of tumor cells, particularly through enhancing cell proliferation, promoting cell migration and invasion, and triggering drug resistance. Importantly, ZEB proteins are regulated by microRNAs (miRs). In this review, we demonstrate the impact that miRs have on cancer therapy, through their targeting of ZEB proteins. MiRs are able to act as onco-suppressor factors and inhibit the malignancy of tumor cells through ZEB1/2 down-regulation. This can lead to an inhibition of epithelial-mesenchymal transition (EMT) mechanism, therefore reducing metastasis. Additionally, miRs are able to inhibit ZEB1/2-mediated drug resistance and immunosuppression. Additionally, we explore the upstream modulators of miRs such as long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs), as these regulators can influence the inhibitory effect of miRs on ZEB proteins and cancer progression.
