Ginger and its constituents in asthma: a mini-review.

OBJECTIVE: The primary objective of this review is to focus on research findings that aim to determine the immunomodulatory action of ginger's active components and the molecular mechanisms that reduce asthma. The study aims to provide an overview of the scientific literature available on ginger's efficacy in treating allergic asthma. DATA SOURCE: The mouse model of asthma has been used to investigate the actions of ginger and its active compounds on allergies and asthma. Various studies and scientific literature on ginger's health-improving qualities and its traditional use have been examined. RESULTS: The findings indicate that ginger and its active ingredients have anti-asthmatic features and a suppressive impact on mast cell production of histamine. Animals given ginger and compounds derived from ginger demonstrate a notable reduction in allergic response, suggesting a significant role in lowering the allergic reaction. CONCLUSION: While ginger shows promise as a potential treatment for allergies and asthma due to its anti-inflammatory, antibacterial, antidiabetic, anticancer, and antioxidant effects, further examination, extrapolation, and confirmation of these results are necessary before utilizing ginger and its active components in human treatments. This review highlights the need for additional research and provides an overview of the current scientific literature on ginger's efficacy in treating allergic asthma.

ß-glucan mitigates ovalbumin-induced airway inflammation by preventing oxidative stress and CD8+ T cell infiltration.

BACKGROUND: Bronchial asthma is a severe respiratory condition characterized by airway inflammation, remodeling, and oxidative stress. ß-Glucan (BG) is a polysaccharide found in fungal cell walls with powerful immunomodulatory properties. This study examined and clarified the mechanisms behind BG's ameliorativeactivitiesin an allergic asthma animal model. METHOD: BG was extracted from Chaga mushroom and characterized using FT-IR, UV-visible, zeta potential, and 1H NMR analysis. The mice were divided into five groups, including control, untreated asthmatic, dexamethasone (Dexa)-treated (1 mg/kg), and BG (30 and 100 mg/kg)-treated groups. RESULTS: BG treatment reduced nasal scratching behavior, airway-infiltrating inflammatory cells, and serum levels of IgE significantly. Additionally, BG attenuated oxidative stress biomarkers by lowering malonaldehyde (MDA) concentrations and increasing the levels of reduced glutathione (GSH), glutathione peroxidase (GPx), and catalase (CAT). Immunohistochemical and flow cytometric analyses have confirmed the suppressive effect of BG on the percentage of airway-infiltrating cytotoxic CD8+ T cells. CONCLUSION: The findings revealed the role of CD8+ T cells in the pathogenesis of asthma and the role of BG as a potential therapeutic agent for asthma management through the suppression of airway inflammation and oxidative stress.

Renewable solar and wind energies on buildings for green ports in Egypt.

Energy management plan is utilized as an optimum strategy by using solar and wind energies, as a new preliminary implementation. The aim of the study is to create an optimum strategy through an optimization of an energy management system. The study implemented an onsite model, two numerical approaches, and an optimization analysis on a Mediterranean port. Two approaches have been used: solar energy is applied experimentally and numerically, and then wind energy is simulated. An optimization analysis integrated the two approaches together to control their operation. The results showed the installed solar panels provided sufficient generated power for the buildings. Also, the simulated wind arrays showed good behavior with increased power coefficient for the wind turbines, for future implementation. These results were validated using the DesignBuilder software and showed accurate values regarding the experiment for solar panels and CFD simulation. Eventually, a Pareto optimality analysis is applied between the solar and wind energies to reveal an energy management plan. Renewable energy offered energy to support the consumption of the port's buildings.
