Item type:Publication, Access status: without files , Effect of lignin and other biopolymers on hyperlipidemia and gut microbiota(Deanship of Scientific Research (DSR) The University of Jordan, 2025-09-24); ; So far, dietary fibers such as lignin, cellulose, pectin, guar gum, and psyllium have been well-studied for their preventive and therapeutical potential using animal and human models, especially for their beneficial effects on chronic metabolic conditions like dyslipidemia and related disorders. Dyslipidemia is a dangerous metabolic disorder related to hypercholesterolemia, coronary artery disease, and coronary heart disease. Earlier research has demonstrated that these dietary fibers can lower high serum lipid levels through different mechanisms. One of the most important mechanisms is the modification of gut microbiota. Increasing the abundance of lactic acid bacteria (LAB), which can metabolize different dietary fibers like lignin, may potentially reduce the cholesterol level. This review aims to provide useful insights and comprehensive discussions about current knowledge related to the properties, and the effects of dietary fibers mainly lignin in controlling hyperlipidemia and their effects on gut microbiota. Google Scholar, Research Gate, and Scopus are the search engines exploited to collect data by using lignin, biopolymers, gut microbiota, and hyperlipidemia as search terms.Publicationtype: Journal Article39 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: with files , Investigation of the Antibacterial Activity of ZnO-Loaded Alginate/Hyaluronic Acid Aerogels for Wound Dressing Applications(Multidisciplinary Digital Publishing Institute (MDPI), 2025-02-15); ; The prevalence of bacterial infections in wounds is a significant challenge to successful wound healing. This study investigates the antibacterial effect of hyaluronic acid and alginate aerogel loaded with zinc oxide nanoparticles as a potential dressing for wound healing. The aerogel composite was synthesized via supercritical gel drying and characterized by scanning electron microscope, Fourier transform infrared spectroscopy, and nitrogen porosimetry. The absorptivity of the prepared aerogel was evaluated, as well as the antibacterial activity, which was evaluated against common wound pathogens, including Staphylococcus aureus and Escherichia coli, using the agar diffusion method. The results show the effective antibacterial properties of the prepared hydrogel and aerogel. Furthermore, the results show water absorption ability of 5791 and 1585% for loaded and unloaded aerogels, respectively. The ZnO released from the aerogel exhibited a rapid release followed by a slow and sustained release. These findings highlight the potential of aerogels based on hyaluronic acid and alginate and loaded with zinc oxide nanoparticles as an innovative antibacterial wound dressing material, which is expected to improve wound healing and reduce the risk of bacterial infections.Publicationtype: Journal Article56 24 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , In vivo tests of a novel wound dressing based on agar aerogelAerogels, especially bio-based ones, present a promising option for wound dressing; specifically, because of their low toxicity, high stability, bio-compatibility, and good biological performance. In this study, agar aerogel was prepared and evaluated as novel wound dressing material in an in vivo rat study. Agar hydrogel was prepared by thermal gelation, after that the water inside the gel was exchanged with ethanol, and finally the alcogel was dried by supercritical CO2. The textural and rheological properties of the prepared aerogel were characterized, showing that the prepared agar aerogels possess high porosity (97–98 %), high surface area (250–330 m2g−1) as well as good mechanical properties and easiness of removal from the wound site. The results of the in vivo experiments macroscopically demonstrate the tissue compatibility of the aerogels in dorsal interscapular injured rat tissue and a shorter wound healing time comparable to that of gauze-treated animals. The histological analysis underpins the reorganisation and healing of the tissue for the injured skin of rats treated with agar aerogel wound dressing within the studied time frame.Publicationtype: Journal ArticleScopus© Citations 6 53 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Evaluation of the orally administered calcium alginate aerogel on the changes of gut microbiota and hepatic and renal function of Wistar rats(Public Library of Science (PLoS), 2021-04-28); ; ; ; The present study evaluates the effect of calcium alginate aerogel as a potential drug carrier, on the liver and kidney functions, and on the gut microbiota of Wistar rats. The studied alginate aerogel was prepared in the form of nanoparticles using the jet cutting technique, and they were characterized in terms of specific surface areas, outer morphology and particle size distribution. For the in vivo study, calcium alginate aerogel was administered orally, and liver and kidney functions were tested for one week and for four weeks in two distinct studies. During the short-term in vivo study, feces samples were collected for bacterial DNA extraction followed by 16S rRNA gene sequencing analyses to detect changes in gut microbiota. Results showed that the prepared alginate aerogel has an average BET-specific surface area of around 540 m /g, with a pore volume of 7.4 cc/g, and pore width of 30–50 nm. The in vivo study revealed that the levels of the studied kidney and liver enzymes didn’t exceed the highest level of the normal range. The study of gut microbiota showed different patterns; certain groups of bacteria, such as Clostridia and Bacteriodia, increased during the aerogels regime and continued to increase after the aerogel was stopped. While other groups such as Erysipelotrichia, and Candidatus saccharibacteria increased during aerogels treatment, and then decreased again after one month. Members of the Bacilli class showed a unique trend, that is, after being the most abundant group (63%) at time 0, their relative abundance decreased dramatically until it reached < 5%; which was the case even after stopping the aerogel treatment. 2Publicationtype: Journal ArticleScopus© Citations 10 147 135
