Electrospun scaffolds based on a PCL/starch blend reinforced with CaO nanoparticles for bone tissue engineering. Int J Biol Macromol 2024; 273:132891. [PMID: 38848852 DOI: 10.1016/j.ijbiomac.2024.132891] [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: 01/16/2024] [Revised: 05/27/2024] [Accepted: 06/02/2024] [Indexed: 06/09/2024]
Abstract
Electrospun nanocomposite scaffolds with improved bioactive and biological properties were fabricated from a blend of polycaprolactone (PCL) and starch, and then combined with 5 wt% of calcium oxide (CaO) nanoparticles sourced from eggshells. SEM analyses showed scaffolds with fibrillar morphology and a three-dimensional structure. The hydrophilicity of scaffolds was improved with starch and CaO nanoparticles, which was evidenced by enhanced water absorption (3500 %) for 7 days. In addition, PCL/Starch/CaO scaffolds exhibited major degradation, with a mass loss of approximately 60 % compared to PCL/Starch and PCL/CaO. The PCL/Starch/CaO scaffolds decreased in crystallinity as intermolecular interactions between the nanoparticles retarded the mobility of the polymeric chains, leading to a significant increase in Young's modulus (ca. 60 %) and a decrease in tensile strength and elongation at break, compared to neat PCL. SEM-EDS, FT-IR, and XRD analyses indicated that PCL/Starch/CaO scaffolds presented a higher biomineralization capacity due to the ability to form hydroxyapatite (HA) in their surface after 28 days. The PCL/Starch/CaO scaffolds showed attractive biological performance, allowing cell adhesion and viability of M3T3-E1 preosteoblastic cells. In vivo analysis using a subdermal dorsal model in Wistar rats showed superior biocompatibility and improved resorption process compared to a pure PCL matrix. This biological analysis suggested that the PCL/Starch/CaO electrospun mats are suitable scaffolds for guiding the regeneration of bone tissue.

Abstract
In this study, the antiproliferative and apoptotic effects of Inula viscosa L. water extract (IVE) on HCT 116 has been examined, and the change in the expression of miRNAs. Phenolic compounds of IVE were determined as µg/g extract using by HPLC-DAD. Quantitative determination of apoptosis, cell viability, IC50 values and miRNAs of the cells were determined during 24, and 48 hours. IVE contain coumarin, rosmarinic acid and chlorogenic acid. According to the findings of our study, the expression of miR-21 and miR-135a1 was upregulated, and miR-145 was downregulated in HCT 116 cells (Control). Additionally, IVE was found to have significant potential in regulating miRNAs, downregulating miR-21, miR-31 and miR-135a1, and upregulating miR-145 in HCT-116 cells. All these results show that the anticancer effect of IVE via regulating miRNAs' expression has been demonstrated for the first time, and may be candidate biomarkers in colorectal cancer.

Astaxanthin Inhibits H 2O 2-Induced Excessive Mitophagy and Apoptosis in SH-SY5Y Cells by Regulation of Akt/mTOR Activation. Mar Drugs 2024; 22:57. [PMID: 38393028 PMCID: PMC10890442 DOI: 10.3390/md22020057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/15/2024] [Accepted: 01/18/2024] [Indexed: 02/25/2024] Open
Abstract
Oxidative stress, which damages cellular components and causes mitochondrial dysfunction, occurs in a variety of human diseases, including neurological disorders. The clearance of damaged mitochondria via mitophagy maintains the normal function of mitochondria and facilitates cell survival. Astaxanthin is an antioxidant known to have neuroprotective effects, but the underlying mechanisms remain unclear. This study demonstrated that astaxanthin inhibited H2O2-induced apoptosis in SH-SY5Y cells by ameliorating mitochondrial damage and enhancing cell survival. H2O2 treatment significantly reduced the levels of activated Akt and mTOR and induced mitophagy, while pretreatment with astaxanthin prevented H2O2-induced inhibition of Akt and mTOR and attenuated H2O2-induced mitophagy. Moreover, the inhibition of Akt attenuated the protective effect of astaxanthin against H2O2-induced cytotoxicity. Taken together, astaxanthin might inhibit H2O2-induced apoptosis by protecting mitochondrial function and reducing mitophagy. The results also indicate that the Akt/mTOR signaling pathway was critical for the protection of astaxanthin against H2O2-induced cytotoxicity. The results from the present study suggest that astaxanthin can reduce neuronal oxidative injury and may have the potential to be used for preventing neurotoxicity associated with neurodegenerative diseases.

Abstract
Non-degradable, slightly degradable, and completely degradable micro/nanoparticles derived from chondroitin sulfate (CS) were synthesized through crosslinking reactions at 50%, 40%, and 20% mole ratios, respectively. The CS particles with a 20% crosslinking ratio show total degradation within 48 h, whereas 50% CS particles were highly stable for up to 240 h with only 7.0 ± 2.8% weight loss in physiological conditions (pH 7.4, 37 °C). Tobramycin and amikacin antibiotics were encapsulated into non-degradable CS particles with high loading at 250 g/mg for the treatment of corneal bacterial ulcers. The highest release capacity of 92 ± 2% was obtained for CS-Amikacin particles with sustainable and long-term release profiles. The antibacterial effects of CS particles loaded with 2.5 mg of antibiotic continued to render a prolonged release time of 240 h with 24 ± 2 mm inhibition zones against Pseudomonas aeruginosa. Furthermore, as a carrier, CS particles significantly improved the compatibility of the antibiotics even at high particle concentrations of 1000 g/mL with a minimum of 71 ± 7% fibroblast cell viability. In summary, the sustainable delivery of antibiotics and long-term treatment of bacterial keratitis were shown to be afforded by the design of tunable degradation ability of CS particles with improved biocompatibility for the encapsulated drugs.

Abstract
AIM This study assessed the effects of topical application of the plant Globularia arabica extract on the diabetic rate of wound closure. METHODS The effect of methanol extracts of G. arabica leaf extract on pro-inflammatory and anti-inflammatory cytokines, as well as the rate of wound contraction, hydroxyproline, and collagen content, was examined using an excision model of wound repair in male rats. RESULTS The healing pattern was also highly related to using 10% plant extract and significantly, (p-Values < 0.025) increased wound contraction and increased Hydroxyproline and collagen expression in both non-diabetic and diabetic rats, demonstrating that G. arabica extract possesses potent wound healing capacity. During the early wound healing phase, IL-6 levels were found to be up-regulated by G. arabica treatment. Increased wound contraction augmented hydroxyproline and collagen content, supporting the early wound healing exhibited by G. arabica. One of the ways for speeding wound healing may be the induction of cytokine production. The result of our study shows that the fibroblast cell line treated with 20µg/ml methanolic extract of G. arabica significantly (p-Values < 0.035) increases the cell migration that indicated the high wound healing activity CONCLUSION: Results suggest that G. arabica may be useful in the topical management of wound healing.

Abstract
![]()
Indolo[2,3-d]benzazepines (indololatonduines)
are rarely discussed in the literature. In this project, we prepared
a series of novel indololatonduine derivatives and their RuII and OsII complexes and investigated their microtubule-targeting
properties in comparison with paclitaxel and colchicine. Compounds
were fully characterized by spectroscopic techniques (1H NMR and UV–vis), ESI mass-spectrometry, and X-ray crystallography,
and their purity was confirmed by elemental analysis. The stabilities
of the compounds in DMSO and water were confirmed by 1H
and 13C NMR and UV–vis spectroscopy. Novel indololatonduines
demonstrated anticancer activity in vitro in a low
micromolar concentration range, while their coordination to metal
centers resulted in a decrease of cytotoxicity. The preliminary in vivo activity of the RuII complex was investigated.
Fluorescence staining and in vitro tubulin polymerization
assays revealed the prepared compounds to have excellent microtubule-destabilizing
activities, even more potent than the well-known microtubule-destabilizing
agent colchicine. Several
synthesized indololatonduine derivatives and their
RuII and OsII complexes were investigated for
their microtubule-targeting properties in comparison with paclitaxel
and colchicine. Fluorescence staining and in vitro tubulin polymerization assays indicate excellent microtubule-destabilizing
activity. The compounds were even more potent than the well-known
microtubule-destabilizing agent colchicine.

Abstract
Ultrasmall MoS2 nanocrystals have unique optoelectronic and catalytic properties that have acquired significant attraction in many areas. We propose here a simple and economical method for synthesizing the luminescent nanocrystals MoS2 using the hydrothermal technique. In addition, the synthesized MoS2 nanocrystals display photoluminescence that is tunable according to size. MoS2 nanocrystals have many advantages, such as stable dispersion, low toxicity and luminescent characteristics, offering their encouraging applicability in biomedical disciplines. In this study, human lung cancer epithelial cells (A549) are used to assess fluorescence imaging of MoS2 nanocrystals. MTT assay, trypan blue assay, flow cytometry and fluorescence imaging results have shown that MoS2 nanocrystals can selectively target and destroy lung cancer cells, especially drug-resistant cells (A549).

Abstract
Trypan blue dye exclusion-based cell viability measurements are highly dependent upon image quality and consistency. In order to make measurements repeatable, one must be able to reliably capture images at a consistent focal plane, and with signal-to-noise ratio within appropriate limits to support proper execution of image analysis routines. Imaging chambers and imaging systems used for trypan blue analysis can be inconsistent or can drift over time, leading to a need to assure the acquisition of images prior to automated image analysis. Although cell-based autofocus techniques can be applied, the heterogeneity and complexity of the cell samples can make it difficult to assure the effectiveness, repeatability and accuracy of the routine for each measurement. Instead of auto-focusing on cells in our images, we add control beads to the images, and use them to repeatedly return to a reference focal plane. We use bead image features that have stable profiles across a wide range of focal values and exposure levels. We created a predictive model based on image quality features computed over reference datasets. Because the beads have little variation, we can determine the reference plane from bead image features computed over a single-shot image and can reproducibly return to that reference plane with each sample. The achieved accuracy (over 95%) is within the limits of the actuator repeatability. We demonstrate that a small number of beads (less than 3 beads per image) is needed to achieve this accuracy. We have also developed an open-source Graphical User Interface called Bead Benchmarking-Focus And Intensity Tool (BB-FAIT) to implement these methods for a semi-automated cell viability analyser.

Abstract
The application of titanium dioxide nanoparticles (TiO2NPs) is on the increase, and so the number of studies dedicated to describing this material's biological effects. Previous studies have presented results indicating the controversial impact of TiO2NPs on cell fate regarding death and survival. We speculate that this may be due to focusing on each of the subject cells as an isolated individual. In this study, we made a difference by looking at the subject cells as an interrelated population. Specifically, we exposed mesenchymal stem cells (MSCs) to TiO2NPs and observed cell death and stimulation of proliferation among the cell population. Our data shows that the exposure to TiO2NPs initiated autophagy, which led to an increase in extracellular Wnt protein levels and increased Wnt/GSK3β/β-catenin/cyclin D1 signalling in the cell population. Autophagy inhibitor repressed the effects of TiO2NPs, which indicates that β-catenin regulation was dependent on TiO2NPs-induced autophagy. The inhibition of β-catenin resulted in dysregulation of cyclin D1 protein expression level. In conclusion, following exposure to TiO2NPs, MSCs undergo autophagy, which induces cell proliferation among the cell population by upregulation of cyclin D1 through the Wnt/GSK3β/β-catenin pathway.

Abstract
Triple-negative breast cancer (TNBC), the most aggressive subtype, does not respond to targeted therapy due to the lack of hormone receptors. There is an urgent need for alternative therapies, including natural product-based anti-cancer drugs, at lower cost. We investigated the impact of a Calligonum comosum L'Hér. methanolic extract (CcME) on the TNBC MDA-MB-231 cell line proliferation and related cell death mechanisms performing cell viability and cytotoxicity assays, flow cytometry to detect apoptosis and cell cycle analysis. The apoptosis-related protein array and cellular reactive oxygen species (ROS) assay were also carried out. We showed that the CcME inhibited the TNBC cell viability, in a dose-dependent manner, with low cytotoxic effects. The CcME-treated TNBC cells underwent apoptosis, associated with a concomitant increase of apoptosis-related protein expression, including cytochrome c, cleaved caspase-3, cyclin-dependent kinase inhibitor p21, and the anti-oxidant enzyme catalase, compared with the untreated cells. The CcME also enhanced the mitochondrial transition pore opening activity and induced G0/G1 cell growth arrest, which confirmed the cytochrome c release and the increase of the p21 expression detected in the CcME-treated TNBC cells. The CcME-treated TNBC cells resulted in intracellular ROS production, which, when blocked with a ROS scavenger, did not reduce the CcME-induced apoptosis. In conclusion, CcME exerts anti-proliferative effects against TNBC cells through the induction of apoptosis and cell growth arrest. In vivo studies are justified to verify the CcME anti-proliferative activities and to investigate any potential anti-metastatic activities of CcME against TNBC development and progression.
