Extracellular Synthesis and Characterization of Silver Nanoparticles-Antibacterial Activity against Multidrug-Resistant Bacterial Strains.

Herein, we report the use of a cell-free extract for the extracellular synthesis of silver nanoparticles (AgNPs) and their potential to address the growing threat of multidrug-resistant (MDR) pathogenic bacteria. The reproducibility of AgNP synthesis was good and AgNP formation kinetics were monitored as a function of various reaction factors via ultraviolet-visible absorption spectroscopy. This green method was dependent on the alkaline pH of the reaction mixture.

Using chemical bath deposition to create nanosheet-like CuO electrodes for supercapacitor applications.

We report the effect of ionic liquids on chemically synthesized hierarchical-like copper oxide (CuO) thin films for supercapacitor applications. Concisely, the CuO thin films were deposited via chemical bath deposition (CBD) using 2-dimethylimidazolium chloride [HPDMIM(C1)], 1-(2',3'-dihydroxypropyl)-3-methylimidazolium chloride [DHPMIM(C1)], and N-(3-methyl-2-oxopropyl)pyridine chloride [MOCPP(C1)] ionic liquid solvents. The effects of the ionic liquid solvents on the morphological evolution of the as-prepared films were analyzed, and electrochemical properties were investigated.

Cellulose⁻Chitosan Antibacterial Composite Films Prepared from LiBr Solution.

Cellulose and chitosan solutions were prepared in 60% LiBr and mixed with a different weight ratio. The washing and drying of the prepared cellulose⁻chitosan composite films were performed under identical conditions. The color of the liquefied mixtures and films was initially transparent but changed from colorless to brownish yellow depending on the ratio of chitosan in the solution.

Adsorptive remediation of cobalt oxide nanoparticles by magnetized α-cellulose fibers from waste paper biomass.

Remediation of engineered-nanomaterials is an up-coming major environmental concern. This study demonstrates adsorptive-remediation of cobalt oxide nanoparticles (CoO NPs) from the water. The α-cellulose-fibers were extracted from waste-paper biomass (WP-αCFs) and magnetized with FeO NPs (M-WP-αCFs).

Paper waste extracted α-cellulose fibers super-magnetized and chitosan-functionalized for covalent laccase immobilization.

Enormous disposal of paper wastes (PW) causing number of environmental problems. PW is efficiently used to extract multifunctional α-cellulose fibers (αCFs). Thus, αCFs extraction from PW, and functionalization with FeO and chitosan were successfully performed for immobilization of laccase.

Chlamydomonas angulosa (Green Alga) and Nostoc commune (Blue-Green Alga) Microalgae-Cellulose Composite Aerogel Beads: Manufacture, Physicochemical Characterization, and Cd (II) Adsorption.

This study presents composite aerogel beads prepared by mixing dissolved cellulose with and cells, respectively, at 0.1, 0.3, and 0.

Long-term trends in intraocular pressure after combined vitrectomy with sub-tenon injection of triamcinolone acetonide.

Purpose: To evaluate the long-term effect of vitrectomy by itself and combined vitrectomy with sub-Tenon injection of triamcinolone acetonide (TA) on intraocular pressure (IOP).

Methods: In a retrospective cohort study, the medical records of 56 eyes of 56 patients who underwent nonemergent vitrectomy and were followed up for at least 24 months were reviewed. Thirty-two eyes of 32 patients underwent combined vitrectomy with sub-Tenon injection of TA.

The effects of nicergoline on corneal nerve regeneration in rat corneas after photorefractive keratectomy.

Purpose: We wanted to investigate the effect of nicergoline on corneal nerve regeneration in rat corneas after photorefractive keratectomy (PRK).

Methods: Twenty Sprague-Dawley male rats were divided into two groups, the control group and the group that had been treated with nicergoline for 4 weeks. Corneal wound healing was evaluated by fluorescein staining after PRK.

Safety of moxifloxacin and voriconazole in corneal storage media on porcine corneal endothelial cells.

Purpose: The aim of this study was to evaluate the safety of moxifloxacin and voriconazole as a supplement in corneal storage media for porcine corneal endothelial cells.

Methods: Twenty-eight eyes were divided into 4 groups. In the control group (the C group), corneal buttons were stored for 3 days in Optisol-GS.

Effect of a single intraoperative sub-Tenon injection of triamcinolone acetonide on the progression of diabetic retinopathy and visual outcomes after cataract surgery.

Purpose: To assess the effect of a single intraoperative sub-Tenon injection of triamcinolone acetonide on the progression of diabetic retinopathy (DR), visual outcomes, and cystoid macular edema (CME) after cataract surgery.

Setting: Department of Ophthalmology and Visual Science, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Methods: This prospective controlled study comprised 46 eyes of 23 diabetic patients.

Hydrogen peroxide-induced cell death in a human retinal pigment epithelial cell line, ARPE-19.

The loss of retinal pigment epithelium (RPE) with aging is related to age-related macular degeneration (AMD). This study was conducted to investigate the mechanism of hydrogen peroxide (H2O2) induced cell death in a human retinal pigment epithelial cell line, ARPE-19. Hydrogen peroxide was added at different concentrations to ARPE-19 cells and cultured.
