Antimicrobial activity of bee-collected pollen and beebread: State of the art and future perspectives
(2020)Bee-collected pollen (BCP) is a well-known functional food. Honey bees process the collected pollen and store it in the hive, inside the comb cells. The processed pollen is called beebread or ambrosia and it is the main ... -
Assessment of remediation of soils, moderately contaminated by potentially toxic metals, using different forms of carbon (charcoal, biochar, activated carbon). Impacts on contamination, metals availability and soil indices
(2022)The present study aims to assess the effect of three forms of carbon, i.e., charcoal, biochar and activated carbon using as soil amendments (or soil conditioners) in two soils, an acid and alkaline one. For this purpose, ... -
Carbon nanotubes and other engineered nanoparticles induced pathophysiology on mesothelial cells and mesothelial membranes
(2018)Nanoparticles have great potential for numerous applications due to their unique physicochemical properties. However, concerns have been raised that they may induce deleterious effects on biological systems. There is ... -
Co-composted biochar derived from rice straw and sugarcane bagasse improved soil properties, carbon balance, and zucchini growth in a sandy soil: A trial for enhancing the health of low fertile arid soils
(2022)Sustainable management of low fertile arid soils using carbon-rich organic amendments such as biochar and compost is of great concern from both agricultural and environmental points of view. The impact of pyrolysis, ... -
Collagen from the marine sponges Axinella cannabina and Suberites carnosus: Isolation and morphological, biochemical, and biophysical characterization
(2017)In search of alternative and safer sources of collagen for biomedical applications, the marine demosponges Axinella cannabina and Suberites carnosus, collected from the Aegean and the Ionian Seas, respectively, were ... -
Curcumin derivatives as potential mosquito larvicidal agents against two mosquito vectors, culex pipiens and aedes albopictus
(2021)Vector-borne diseases have appeared or re-emerged in many Southern Europe countries making the transmission of infectious diseases by mosquitoes (vectors) one of the greatest worldwide health threats. Larvicides have been ... -
Development and evaluation of liposomal nanoparticles incorporating dimethoxycurcumin. In vitro toxicity and permeability studies
(2022)Liposomes belong to the class of drug delivery nanosystems and are widely used for the incorporation and delivery of lipophilic drug molecules. The present work deals with the physicochemical characterization of different ... -
Estimating remobilization of potentially toxic elements in soil and road dust of an industrialized urban environment
(2022)The mobility of potentially toxic elements (PTEs) is of paramount concern in urban settings, particularly those affected by industrial activities. Here, contaminated soils and road dusts of the medium-size, industrialized ... -
Expanding the use of biobeds: Degradation and adsorption of pesticides contained in effluents from seed-coating, bulb disinfestation and fruit-packaging activities
(2019)Agro-food industries that use pesticides constitute significant point sources for the contamination of natural water resources. Despite that, little is known about the treatment of their pesticide-contaminated effluents. ... -
Factors mediating lipofection potency of a series of cationic phosphonolipids in human cell lines
(2006)A series of cationic liposomes known as cationic phosphonolipids (CPs) were evaluated as vehicles for in vitro gene transfer in K562 erythroleukemia cells and 5637 epithelial carcinoma cells. For each CP and target cell ... -
Green remediation of toxic metals contaminated mining soil using bacterial consortium and Brassica juncea
(2021)Microorganism-assisted phytoremediation is being developed as an efficient green approach for management of toxic metals contaminated soils and mitigating the potential human health risk. The capability of plant growth ... -
HLA class II peptide-binding-region analysis reveals funneling of polymorphism in action
(2021)Background: HLA-class II proteins hold important roles in key physiological processes. The purpose of this study was to compile all class II alleles reported in human population and investigate patterns in pocket variants ... -
Identification and characterization of tebuconazole transformation products in soil by combining suspect screening and molecular typology
(2016)Pesticides generate transformation products (TPs) when they are released into the environment. These TPs may be of ecotoxicological importance. Past studies have demonstrated how difficult it is to predict the occurrence ... -
