Abstract
Multidrug-resistant (MDR) bacteria-caused infections have been a major threat to human health. The abuse of conventional antibiotics accelerates the generation of MDR bacteria and makes the situation worse. The emergence of nanomaterials holds great promise for solving this tricky problem due to their multiple antibacterial mechanisms, tunable antibacterial spectra, and low probabilities of inducing drug resistance. In this review, we summarize the mechanism of the generation of drug resistance, and introduce the recently developed nanomaterials for dealing with MDR bacteria via various antibacterial mechanisms. Considering that biosafety and mass production are the major bottlenecks hurdling the commercialization of nanoantibiotics, we introduce the related development in these two aspects. We discuss urgent challenges in this field and future perspectives to promote the development and translation of nanoantibiotics as alternatives against MDR pathogens to traditional antibiotics-based approaches.

[PMID: 37739095 DOI: 10.1016/j.ijpharm.2023.123432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 09/16/2023] [Accepted: 09/19/2023] [Indexed: 09/24/2023]
Abstract
Extended release formulations play a crucial role in the pharmaceutical industry by maintaining steady plasma levels, reducing side effects, and improving therapeutic efficiency and compliance. One commonly used method to develop extended release formulations is direct compression, which offers several advantages, such as simplicity, time savings, and cost-effectiveness. However, successful direct compression-based extended release formulations require careful assessment and an understanding of the excipients' attributes. The scope of this work is the characterization of the compaction behavior of some matrix-forming agents and diluents for the development of extended release tablets. Fifteen excipients commonly used in extended release formulations were evaluated for physical, compaction and tablet properties. Powder properties (e.g., particle size, flow properties, bulk density) were evaluated and linked to the tablet's mechanical properties in a fully integrated approach, and data were analyzed by constructing a principal component analysis (PCA). Significant variability was observed among the various excipients. The present work successfully demonstrates the applicability of PCA as an effective tool for comparative analysis, pattern and clustering recognition and correlations between excipients and their properties, facilitating the development and manufacturing of direct compressible extended release formulations.

Abstract
The potential of nanoparticles as effective drug delivery systems combined with the versatility of fibers has led to the development of new and improved strategies to help in the diagnosis and treatment of diseases. Nanoparticles have extraordinary characteristics that are helpful in several applications, including wound dressings, microbial balance approaches, tissue regeneration, and cancer treatment. Owing to their large surface area, tailor-ability, and persistent diameter, fibers are also used for wound dressings, tissue engineering, controlled drug delivery, and protective clothing. The combination of nanoparticles with fibers has the power to generate delivery systems that have enhanced performance over the individual architectures. This review aims at illustrating the main possibilities and trends of fibers functionalized with nanoparticles, focusing on inorganic and organic nanoparticles and polymer-based fibers. Emphasis on the recent progress in the fabrication procedures of several types of nanoparticles and in the description of the most used polymers to produce fibers has been undertaken, along with the bioactivity of such alliances in several biomedical applications. To finish, future perspectives of nanoparticles incorporated within polymer-based fibers for clinical use are presented and discussed, thus showcasing relevant paths to follow for enhanced success in the field.

Propensity score matching analysis to evaluate efficacy of polyethylene oxide adhesive on preventing delayed bleeding after gastric endoscopic submucosal dissection. Sci Rep 2022; 12:4538. [PMID: 35297400 PMCID: PMC8927376 DOI: 10.1038/s41598-022-08499-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 03/07/2022] [Indexed: 02/07/2023] Open
Abstract
Regardless of technical advancements, delayed bleeding is still a common adverse event after gastric endoscopic submucosal dissection (ESD), often occurring in the early postoperative phase. This study aimed to evaluate the efficacy of a newly designed polyethylene oxide (PEO) adhesive for preventing delayed gastric bleeding. Patients who underwent gastric ESD between December 2017 and December 2020 at three Chinese institutions were retrospectively reviewed. Patients receiving PEO application on gastric post-ESD ulcers were included in the PEO group, and patients without this procedure were included in the control group. To minimize potential bias, propensity score matching was performed, and sex, age, lesion size, lesion morphology, ulceration, localization, procedure time, frequency of major intraoperative bleeding, resected specimen size, lesion histopathology, submucosal invasion and the taking of antithrombotic drugs were included as matching factors. The incidence of delayed bleeding and time to bleeding were compared between both groups. After propensity score matching, 270 patients (135 per group) were included in the analysis. The delayed bleeding rate in the PEO group was significantly lower than that in the control group (1.5%, 2/135 vs. 8.9%, 12/135, P = 0.006). The median time (range) to bleeding was 4.5 (4–5) days in the PEO group and 2 (1–15) days in the control group, with no significant difference (P = 0. 198). PEO demonstrated a significant effect in reducing the rate of delayed bleeding. Further study is warranted to confirm the efficacy of PEO for bleeding that occurs in the early phase after gastric ESD.

J Chromatogr A 2021; 1659:462640. [PMID: 34731751 DOI: 10.1016/j.chroma.2021.462640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 10/19/2021] [Accepted: 10/20/2021] [Indexed: 11/29/2022]
Abstract
This study investigated the experimental conditions needed to obtain molecular weight distribution (MWD) of ultrahigh MW poly(ethylene oxide) (PEO) using size exclusion chromatography (SEC) hyphenated with a multiangle light scattering photometer (MALS) and a differential refractive index detector (RI). Ultrahigh MW components yielded non-linear angular dependency in scattered light intensities. The first-order linear fitting using Zimm formalism resulted in significant differences in MW depending on if the signals from detector 4 to 16 were used in the fitting or only five low-angles from 4 to 8 were used. In contrast, no significant differences in MW were obtained for lower MW PEO samples (equal or less than 1000 KDa) between the two fitting approaches. It was thus proposed to use only the five low-angles to derive MW for a sample with broad polydispersity including both ultrahigh and low MW components. The SEC separation was done using one column designed for ultrahigh MW polymer separation connected with another mixed-bed column. The ultrahigh MW column allowed separation and characterization of polymeric components in the MW range between 10 and 50 million Dalton (MDa) and the size range between 300 and 600 nm in radius of gyration (Rg). Online calibration curves were obtained from the linear fittings of MW as a function of elution volume. MW polydispersity was derived from the online calibration curve showing that the ultrahigh MW PEO had higher polydispersity than the lower MW samples. The double logarithmic plot of radius of gyration versus MW indicated that both ultrahigh MW and low MW PEO would adopt expanded coil conformations in the aqueous solution.
