Development of nanofibrous scaffolds containing polylactic acid modified with turmeric and hydroxyapatite/vivianite nanoparticles for wound dressing applications. Int J Biol Macromol 2024; 259:128624. [PMID: 38061519 DOI: 10.1016/j.ijbiomac.2023.128624] [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: 08/14/2023] [Revised: 11/25/2023] [Accepted: 12/02/2023] [Indexed: 01/14/2024]
Abstract
Damaging the outer layer of the body (the skin) has been a common issue for decades. Fabrication of nanofibrous membranes via the electrospinning technique for the sake of making the wound healing process more facile has caught a lot of interest. For this purpose, a polymeric scaffold of polylactic acid (PLA) was doped with nanoparticles with different concentrations of turmeric/hydroxyapatite/vivianite/graphene oxide. The obtained membrane was tested by XRD, SEM, FTIR, and XPS. The surface topography of the scaffold has experienced changes upon adding different concentrations of the nanoparticles. The contact angle was measured by water droplets. It accentuated change in CA starting from 43.9o for pure condition of PLA to 67.7o for PLA/turmeric/vivianite. The thermogravimetric analysis (TGA) test stated that the PLA scaffold features are thermally stable in relatively high-temperature conditions initiating from room temperature to about 300 °C, meeting the maximum loss in mass of about 5 %. The cell viability was carried out in prepared vitro for the sample which contains PLA/turmeric/vivianite/GO, it was elucidated that the IC50 was around 3060 μg/ml.

Abstract
Autoimmune diseases usually arise as a result of an aberrant immune system attack on normal tissues of the body, which leads to a cascade of inflammatory reactions. The immune system employs different types of protective and anti-inflammatory cells for the regulation of this process. Curcumin is a known natural anti-inflammatory agent that inhibits pathological autoimmune processes by regulating inflammatory cytokines and their associated signaling pathways in immune cells. Due to the unstable nature of curcumin and its susceptibility to either degradation, or metabolism into other chemical entities (i.e., metabolites), encapsulation of this agent into various nanocarriers would appear to be an appropriate strategy for attaining greater beneficial effects from curcumin as it pertains to immunomodulation. Many studies have focused on the design and development of curcumin nanodelivery systems (micelles, dendrimers, and diverse nanocarriers) and are summarized in this review in order to obtain greater insight into novel drug delivery systems for curcumin and their suitability for the management of autoimmune diseases.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory disease, which deleteriously affects the lower end of the gastrointestinal tract, i.e., the colon and the rectum. UC affects colonic inflammatory homeostasis and disrupts intestinal barrier functions. Intestinal tissue damage activates the immune system and collectively worsens the disease condition via the production of various cytokines. Ongoing therapeutics of UC have marked limitations like rapid clearance, extensive first-pass metabolism, poor drug absorption, very low solubility, bioavailability, etc. Because of these restrictions, the management of UC demands a rational approach that selectively delivers the drug at the site of action to overcome the therapeutic limiting factors. Metallic nanoparticles (NPs) have good therapeutic efficacy against colitis, but their uses are limited due to adverse effects on the biological system. In this study, we have used biocompatible thiol-functionalized cellulose-grafted copper oxide nanoparticles (C-CuI/IIO NPs) to treat UC. The metal NPs alleviated the colitis condition as evidenced by the colon length and observed physical parameters. Analysis of histopathology demonstrated the recovery of the colon architecture damaged by dextran sulfate sodium-induced colitis. Treatment with C-CuI/IIO NPs reduced the disintegration of goblet cells and the retainment of sulfomucin. Significant downregulation of inflammatory markers like MPO activity, as well as levels of nitrite and TNF-α, was found following C-CuI/IIO NP treatment. The observations from the study suggested that intrarectal treatment of colitis with cellulose-based C-CuI/IIO NPs successfully combated the intestinal inflammatory condition.

Abstract
Curcumin (CUR) is a natural hydrophobic compound, which is available in turmeric rhizome. It has several bioactivities including antioxidant, anti-obesity, anti-diabetic, cardioprotective, anti-inflammatory, antimicrobial, anticancer, and other activities. Despite its medical and biological benefits, it is using in limitations because of its hydrophobicity and sensitivity. These unfavorable conditions further reduced the bioavailability (BA) and biological efficacy of CUR. This review summarizes the stability and BA of free- and encapsulated-CUR, as well as comprehensively discusses the potential biological activity of CUR-loaded various micro-/nano-encapsulation systems. The stability and BA of CUR can be improved via loading in different encapsulation systems, including nanoemulsions, liposomes, niosomes, biopolymer-based nanoparticles, nano-hydrogel, and others. Biopolymer-based nanoparticles (especially poly lactic-co-glycolic acid (PLGA), zein, and chitosan) and nano-gels are the best carriers for encapsulating and delivering CUR. Both delivery systems are suitable because of their excellent functional properties such as high encapsulation efficiency, well-stability against unfavorable conditions, and can be coated using other encapsulation systems. Based on available evidences, encapsulated-CUR exerted greater biological activities especially anticancer (breast cancer), antioxidant, antidiabetic, and neuroprotective effects.

Abstract
Ulcerative colitis (UC) is an idiopathic bowel disease involving chronic inflammation and ulcers in colon and implicates severe epithelial damage with disruption in colon homeostasis. Presently existing treatments possess serious concerns like off target effects and adverse reactions, drug inactivation, poor absorption and other complications resulting in poor bioavailability. In context of high risk of thrombotic events in UC patients, heparin can offer appreciable benefits in UC management due to its remarkable anti-coagulating properties, its ability to intervene inflammatory pathways and acceleration of wound healing process. However, oral administration of heparin being impractical due to harsh gastric acidic environment and heparin degradation, conventional heparin administration is done via intravenous route. Present study was designed to formulate, characterize and evaluate sustained release heparin formulation in mice model of experimental colitis. Heparin liposomes (HLp) were formulated by solvent evaporation and extrusion process and possessed hydrodynamic diameter of 242 ± 4.3 nm. Size, shape and surface morphology was confirmed by TEM, SEM and AFM micrographs while encapsulation efficiency and loading of heparin in optimized HLp were 59.61% and 12.27%, respectively. HLp enema administration ameliorated gross disease indices like body weight, colon length, stool consistency, fecal occult blood. Further, anti-inflammatory efficacy of HLp was established in histopathological analysis where HLp appreciably restored protective mucin layer, colon epithelial mucosal histoarchitecture and considerably attenuated mast cell infiltration in colon epithelia. Overall, results of this study indicate that HLp demonstrated an appreciable therapeutic efficacy in experimental colitis and these results are attributed to their ability to suppress inflammation.

Abstract
BACKGROUND Delayed gastric emptying play an important role in the pathology of functional dyspepsia. Owing to their functional attributes in alleviating the gastrointestinal disorders, single or polyherbal formulations have gained attention to treat the symptoms of functional dyspepsia. We have investigated the safety and efficacy of a novel formulation of Ferula asafoetida oleo resin and standardized Silybum marianum extract (Asdamarin). METHODS The effect of asdamarin on delayed gastric emptying was investigated in Sprague Dawley rats using phenol red method. The acute and sub-acute oral toxicity was evaluated in wistar rats following OECD guidelines 425 and 407 respectively. The data were analyzed by one-way ANOVA using GraphPad Prism 5.0 software. RESULTS Oral administration of Asdamarin dose-dependently improved the delay in gastric emptying as evident from the significant increase in the gastrointestinal transit time (p < 0.001). The LD50 of asdamarin was estimated to be more than 2000 mg/kg. Further, in the 28-day sub-acute toxicity study, the administration of 250, 500 and 1000 mg/kg of Asdamarin did not significantly altered the feed and water consuption, body weight change, biochemical and haematological parameters compared to control animals. Macroscopic and histopathological examination of vital organs revealed no toxic signs. CONCLUSION The preliminary data from the present study provides the first evidence on the possible effectiveness of novel formulation of F. Asafoatida and S. marianum extracts in alleviating the associated symptoms of functional dyspepsia. The toxicity data indicated that Asdamarin can be considered safe up to 1000 mg/kg dose.

Abstract
The agro-industrial waste obtained after the isolation of bio-constituents from ginger is available in abundance. In the present study, the effective isolation of ginger nanofibers (GNF) was carried out by acid hydrolysis and high pressure homogenization to get cellulose nanofibers with 100 to 200 nm width. Bionanocomposites were also prepared by reinforcing different ratios of (1% to 7%) GNF with chitosan (CS) and polyvinyl alcohol (PVA) matrices by solvent cast method and the 5% GNF with CS and PVA resulted a high mechanical strength composites than others. The surface morphology and structural analysis of the composites were identified by Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) methods. The inhibitory effect of 5% GNF bionanocomposites against Bacillus cereus, Escherichia coli, Staphylococcus aureus and Salmonella typhimurium indicated good antibacterial activity of the nanocomposites due to the addition of GNF in the biopolymer matrices. The use of GNF will help to increase the economic values of agricultural waste and the characteristic properties of GNF derived bionanocomposites could be possibly used in medical and packaging areas.

Abstract
Turmeric nanofibers (TNF) were used as reinforcement in the gum arabic (GA), maltodextrin (MDX) and polyethylene glycol (PEG) matrices to enhance the physicochemical properties. The TNF were prepared from turmeric spent by acid hydrolysis accompanied by high pressure homogenization. The thermal and mechanical properties, structure morphology and antimicrobial activities of the prepared nanocomposites were investigated. Differential scanning calorimetry (DSC) data indicate that the addition of TNF significantly increased the onset temperature (To), peak temperature (Tp) and conclusion temperature (Tc) of the melting peaks of nanocomposites, but considerably decreased the enthalpy change values. The tensile properties showed that the addition of TNF enhanced mechanical properties due to the formation of networks within the GA, MDX and PEG. The scanning electron microscopy (SEM) images revealed the films of GA-TNF and MDX-TNF show smooth, homogenous surface due to intermolecular hydrogen bonding, and the film of PEG-TNF shows good dispersion of TNF with PEG matrix with rough surface because of strong interfacial adhesion between TNF and PEG and strong hydrogen bonding, which are further confirmed by the FT-IR spectroscopy. XRD results exhibited the disappearances of peaks of TNF indicating the reinforcement of TNF in the prepared nanocomposite matrices. The antibacterial tests show the prepared nanocomposites exhibited excellent antibacterial performance against Bacillus cereus, Escherichia coli, Staphylococcus aureus and Salmonella typhimurium.

Abstract
Ginger residues left after the extraction of active ingredients from ginger rhizomes are considered to be a bio-waste, available in abundance and very rarely used. Extraction and isolation of natural nanofibers from the agro-waste is economical, environmentally benign, and an alternate strategy to replace synthetic fibers. Here, we report, for the first time, the isolation of ginger nanofibers (GNF) from ginger rhizomes spent by acid hydrolysis and followed by high-pressure homogenization. Scanning electron microscopy was utilized to identify the surface morphology of the GNF and the widths ranged between 130 to 200 nm. Structural analysis of GNF was identified by Fourier transform infrared spectroscopy, Differential scanning calorimetry, and X-ray diffraction methods. This GNF was used to make natural nanocomposites by the solvent-casting method reinforcement, using potato starch (PS) and tapioca starch (TS), and was characterized through various methods. These composites were prepared by the addition of 1, 3, 5, and 7 weight % of GNF with PS or TS. Among these, 5% of the GNF composites of these starches showed very high mechanical properties. The antibacterial test showed that the bionanocomposites with 5% GNF exhibited good antibacterial activity against Bacillus cereus, Escherichia coli, Staphylococcus aureus, and Salmonella typhimurium, due to the addition of GNF in the biopolymer matrices. The viable use of GNF from the unexploited ginger agro-waste would create additional profit and it would help to diminish a large amount of waste generation. Thus, the developed bio-composite could also be employed for development of packing materials and be used in medical applications, such as wound healing pads and medical disposables.

Antipleuritic and Vascular Permeability Inhibition of the Ethyl Acetate-Petroleum Ether Stem Bark Extract of Maerua angolensis DC (Capparaceae) in Murine. Int J Inflam 2018; 2018:6123094. [PMID: 30112161 PMCID: PMC6077359 DOI: 10.1155/2018/6123094] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Revised: 06/04/2018] [Accepted: 06/12/2018] [Indexed: 01/24/2023] Open
Abstract
Maerua angolensis has been used traditionally in the management of pain, arthritis, and rheumatism in Ghana and Nigeria but no scientific evidence is currently available to give credence to its folkloric use. The aim of this study was therefore to evaluate the anti-inflammatory effects of a stem bark extract of Maerua angolensis DC (MAE) in acute inflammatory models. The effects of MAE (30-300 mg kg−1) on neutrophil infiltration, exudate volume, and endogenous antioxidant enzymes in lung tissues and lung morphology were evaluated with the carrageenan induced pleurisy model in Sprague Dawley rats. The effects of MAE (30-300 mg kg−1) on vascular permeability were also evaluated in the acetic acid induced vascular permeability in ICR mice. MAE significantly reduced neutrophil infiltration, exudate volume, and lung tissue damage in carrageenan induced pleurisy. MAE increased the activities of antioxidant enzymes glutathione, superoxide dismutase, and catalase in lung tissues. The extract was also able to reduce myeloperoxidase activity and lipid peroxidation in lung tissues in carrageenan induced rat pleurisy. Vascular permeability was also attenuated by the extract with marked reduction of Evans blue dye leakage in acetic acid induced permeability assay. The results indicated that Maerua angolensis is effective in ameliorating inflammation induced by carrageenan and acetic acid. It also has the potential of increasing the activity of endogenous antioxidant enzymes.

Abstract
Crohn's Disease (CD) and Ulcerative Colitis (UC) result from an overreaction of the bowel to multifactorial stimuli leading to discomfort, pain, and it is associated with high morbidity and lethality. The medications commonly used are expensive and associated with multiple side effects. Curcuma longa exerts anti-inflammatory and antioxidant actions and has shown positive effects on CD and UC treatment, possibly due to the presence of curcuminoids. The objective of this review was to evaluate the role of curcuminoids in the treatment of IBD. A search for articles associating curcuminoids and CD and UC was performed using MEDLINE-PubMed. It has been found that curcumin can reduce oxidative stress and inhibit the migration of neutrophils and inducible nitric oxide synthase in the intestine. It may also improve micro and macroscopic lesions, prevent apoptosis of intestinal cells and also induce the restoration of the mitogen-activated protein kinase immune reaction. As the incidence of CD and UC is growing in many populations, there is an urgency to find an appropriate and accessible therapeutic approach to improve quality of life of patients. The use of curcumin is cheap, efficient and associated with no side effects, and may become an alternative to the IBD treatment.
