Açai ( Euterpe oleracea Mart.) supplementation promotes histological and ultrastructural changes in rats' alveolar bone. Heliyon 2024; 10:e31067. [PMID: 38807891 PMCID: PMC11130704 DOI: 10.1016/j.heliyon.2024.e31067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 04/11/2024] [Accepted: 05/09/2024] [Indexed: 05/30/2024] Open
Abstract
The açai juice contains high concentrations of phenolic compounds, including cyanidin-3-glucoside and others flavonoids. The aim of this study was to evaluate the impact of açai supplementation on healthy mandibular alveolar bone in male albino rats of the Wistar strain. 24 rats were divided into 3 groups, in which one group received a daily dose of saline solution and the other two groups were treated with daily doses of clarified açai juice for 14 or 28 days. After the experiment, hemimandibles were collected and analyzed using Scanning Electron Microscopy (SEM), histological assessments, and micro-CT. Results showed changes in the integrity of the alveolar bone as seen in SEM, increased osteocyte density and higher collagen matrix area in the açai group compared to the control group as seen in histological analysis, and increased bone volume, trabecular thickness and number, and cortical bone as seen in micro-CT analysis. The space between bone trabeculae showed no difference among the groups. These results suggest that açai supplementation may have a structural change effect on alveolar bone, but further research is needed to confirm these findings in humans and to determine the exact mechanisms behind these effects.

Ipomoea carnea mitigates ethanol-induced ulcers in irradiated rats via Nrf2/HO -1 pathway: an in vivo and in silico study. Sci Rep 2024; 14:3469. [PMID: 38342928 PMCID: PMC10859386 DOI: 10.1038/s41598-024-53336-1] [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: 11/01/2023] [Accepted: 01/31/2024] [Indexed: 02/13/2024] Open
Abstract
The aim of this study was to investigate the potential of Ipomoea carnea flower methanolic extract (ICME) as a natural gastroprotective therapy against ethanol-induced gastric ulcers, particularly in individuals exposed to ionizing radiation (IR). The study focused on the Nrf2/HO-1 signaling pathway, which plays a crucial role in protecting the gastrointestinal mucosa from oxidative stress and inflammation. Male Wistar rats were divided into nine groups, the control group received distilled water orally for one week, while other groups were treated with ethanol to induce stomach ulcers, IR exposure, omeprazole, and different doses of ICME in combination with ethanol and/or IR. The study conducted comprehensive analyses, including LC-HRESI-MS/MS, to characterize the phenolic contents of ICME. Additionally, the Nrf2/HO-1 pathway, oxidative stress parameters, gastric pH, and histopathological changes were examined. The results showed that rats treated with IR and/or ethanol exhibited histopathological alterations, increased lipid peroxidation, decreased antioxidant enzyme activity, and reduced expression levels of Nrf2 and HO-1. However, pretreatment with ICME significantly improved these parameters. Phytochemical analysis identified 39 compounds in ICME, with flavonoids, hydroxybenzoic acids, and fatty acids as the predominant compounds. Virtual screening and molecular dynamics simulations suggested that ICME may protect against gastric ulceration by inhibiting oxidative stress and inflammatory mediators. In conclusion, this study demonstrates the potential of ICME as a natural gastroprotective therapy for preventing gastric ulcers. These findings contribute to the development of novel interventions for gastrointestinal disorders using natural plant extracts particularly in individuals with a history of radiation exposure.

Green Synthesis of Gold Nanoparticles with Curcumin or Açai in the Tissue Repair of Palatal Wounds. Antioxidants (Basel) 2023; 12:1574. [PMID: 37627569 PMCID: PMC10451912 DOI: 10.3390/antiox12081574] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 07/27/2023] [Accepted: 08/02/2023] [Indexed: 08/27/2023] Open
Abstract
This study aimed to evaluate and compare the effects of treatment with gold nanoparticles (GNPs) reduced with Curcumin (Curcuma longa L.) or Açai (Euterpe oleracea) to a standard commercial treatment of the pharmacological type (Omcilon®) and an electrophysical agent (photobiomodulation) in the palatal wounds of rats. As for the in vitro assay, a cell viability test was performed to assess the toxicity of the synthesized nanoparticles. In vivo assay: 60 Wistar rats were divided into five groups (n = 12): I. Palatal Wound (PW); II. PW + Photobiomodulation (PBM); III. PW + Omcilon®; IV. PW + GNPs-Cur (0.025 mg/mL); V. PW + GNPs-Açai (0.025 mg/mL). Animals were first anesthetized, and circular lesions in the palatine mucosa were induced using a 4 mm-diameter punch. The first treatment session started 24 h after the injury and occurred daily for 5 days. The animals were euthanized, and the palatal mucosa tissue was removed for histological, biochemical, and molecular analysis. GNPs-Açai were able to significantly reduce pro-inflammatory cytokines and increase anti-inflammatory ones, reduce oxidant markers, and reduce inflammatory infiltrate while increasing the collagen area and contraction rate of the wound, along with an improved visual qualification. The present study demonstrated that the proposed therapies of GNPs synthesized greenly, thus associating their effects with those of plants, favor the tissue repair process in palatal wounds.

Impact of Green Extraction on Curcuminoid Content, Antioxidant Activities and Anti-Cancer Efficiency (In Vitro) from Turmeric Rhizomes ( Curcuma longa L.). Foods 2022; 11:foods11223633. [PMID: 36429224 PMCID: PMC9689051 DOI: 10.3390/foods11223633] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 11/09/2022] [Accepted: 11/10/2022] [Indexed: 11/16/2022] Open
Abstract
Turmeric (Curcuma longa L.) powder is widely used as a spice and seasoning in Asian countries. This study investigated the effect of turmeric extracts on the anticancer activity of Huh7 and HCT 116 cells. The curcumin bioactive compounds were extracted using various methods such as microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE) and traditional extraction (TDE). The yield of dried extracts from MAE was found to be the highest at 17.89%, followed by UAE and TDE, with 11.34% and 5.54%, respectively. Antioxidant activities such as TPC, DPPH and FRAP from MAE were higher than those of UAE and TDE. The total curcuminoid contents from the novel extractions were higher than those from traditional extraction methods. For instance, curcuminoid contents from MAE, UAE and TDE were 326.79, 241.17 and 215.83 mg/g, respectively. Due to having the highest bioactive compounds and extraction yield, turmeric extract from MAE was used to investigate the potential anticancer properties. The extract showed significant cytotoxic potential against the human liver (Huh7) and human colon (HCT116) cell lines, in concentrations ranging from 31.25 to 1000.00 µg/mL. Turmeric extracts using MAE have potential anticancer effects on Huh7 and HCT116 cells. This study serves as scientific data for the chemotherapeutic properties of turmeric extracts and their use as functional ingredients.

Açaí (Euterpe oleracea Mart.) Attenuates Oxidative Stress and Alveolar Bone Damage in Experimental Periodontitis in Rats. Antioxidants (Basel) 2022; 11:antiox11101902. [PMID: 36290625 PMCID: PMC9598833 DOI: 10.3390/antiox11101902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 08/18/2022] [Accepted: 08/26/2022] [Indexed: 11/25/2022] Open
Abstract
Açaí (Euterpe oleracea Mart.) juice is rich in phenolic compounds with high antioxidant capacity. It has been observed that the use of antioxidants may be an additional strategy to nonsurgical periodontal therapy as well as to prevent alveolar bone loss. Thus, the objective of this study was to investigate the effects of açaí supplementation on experimental periodontitis in rats. Twenty male Rattus norvegicus (Wistar) rats were assigned into control, açaí, experimental periodontitis, and experimental periodontitis with açaí supplementation groups. Periodontitis was induced by placing ligatures around the lower first molars. Animals in the açaí groups received 0.01 mL/g of clarified açaí juice for 14 days by intragastric gavage. At the end of the experimental period, blood was collected to assess the reduced glutathione (GSH), Trolox equivalent antioxidant capacity (TEAC), and lipid peroxidation (TBARS) levels. Moreover, hemimandibles were analyzed by micro-computed tomography (micro-CT) for alveolar bone loss and bone quality. Açaí supplementation increased blood total antioxidant capacity and decreased lipid peroxidation. It also reduced alveolar bone loss when compared to the experimental periodontitis group. Moreover, clarified açaí per se modulated the oxidative biochemistry and bone microstructure. Thus, açaí may be considered a viable alternative for managing periodontal oxidative stress and preventing alveolar bone loss.
