Purpose The current study evaluated the cell attachment capability and long-term stability of 5 - fluorouracil (5-FU) loaded alginate-gelatin scaffolds reinforced with zinc-doped hydroxyapatite (Zn-HA). Methods Zn-HA (2% and 6% Zn) was prepared and evaluated for the crystalline nature, chemical structure, and microstructure of hydroxyapatite (HA). Blank and 5-FU loaded alginate-gelatin-Zn-HA scaffolds were prepared and evaluat...
The study evaluates the phytoremediation potential of five wild macrophytes ‒ Setaria geminata (Forssk.) Veldkamp, Ceratophyllum demersum L., Myriophyllum spicatum L., Persicaria senegalensis (Meisn.) Soják, and Ludwigia adscendens subsp. diffusa (Forssk.) P.H. Raven‒ for iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) on the shore of two islands in Luxor governorate, Egypt: Armant (sites 1 and 2) and Aqalata (site 3). T...
Sustainable agriculture aims to provide food needs while improving soil health and protecting it from degradation and contamination from excessive chemical fertilizer use. Sandy-textured soils have low fertility and water-holding capacity. This study assessed the integrated impact of super absorbent polymers (SAPs) and biofertilizer application on the soil chemical characteristics and wheat growth parameters in sandy loam soil...
The use of phytobiotic as functional feed additives is a promising inducer for growth performance and immune response in the Pacific whiteleg shrimp ( Litopenaeus vannamei ). It can be also commercially applied in combination with chemotherapeutic agents and vaccines. This study was carried out to evaluate the use of a commercial phytobiotic feed additive, Sanacore® GM, containing vegetable fatty acids and inactivated Saccharo...
Adsorption behavior of Mo(VI) from aqueous solutions using tungstate-modified magnetic nanoparticleNARA Subscribed
A new magnetic nanoparticle modified with sodium tungstate (Mnp-Si-W) was synthesized and employed for the sorption of molybdenum from aqueous solutions. The prepared nanoparticles (Mnp-Si-W) were characterized by different advanced techniques. Different parameters that influenced the adsorption percent of Mo(VI) were investigated using a batch process. Based on a systematic investigation of the adsorption isotherms and kineti...
Synthesis of Nano-silica Oxide for Heavy Metal Decontamination from Aqueous SolutionsNARA Subscribed
In the current study, nano-silica oxide (nano-SiO 2 ) was fabricated via the sol-gel technique. Then, the prepared nano-SiO 2 was characterized using X-ray diffractometer (XRD), transmission electron microscopy (TEM) coupled with energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) specific surface area analysis. Furthermo...
Identifying tipping points in the relationship between aridity and gross nitrogen (N) cycling rates could show critical vulnerabilities of terrestrial ecosystems to climate change. Yet, the global pattern of gross N cycling response to aridity across terrestrial ecosystems remains unknown. Here, we collected 14,144 observations from 451 15 N‐labeled studies and used segmented regression to identify the global threshold respons...
This study was conducted to evaluate the dietary effects of chromium methionine (Cr-Meth) chelate on growth performance, oxidative stress parameters, blood biochemistry, and carcass traits of broiler chickens. An experiment was conducted on 34,000 1-day-old straight-run broiler chicks (Indian River; 42.0 ± 0.03) at a commercial farm. The chicks were divided randomly into 3 groups; the first group contained 17,000 birds, which...
Ameliorative effect of flavocoxid on cyclophosphamide-induced cardio and neurotoxicity via targeting the GM-CSF/NF-κB signaling pathwayNARA Subscribed
Cyclophosphamide (Cyclo) is a chemotherapeutic agent used as an immunosuppressant and as a treatment for many cancerous diseases. Many previous pieces of literature proved the marked cardio and neurotoxicity of the drug. Thus, this research provides evidence on the alleviative effect of flavocoxid on the cardiac and brain toxicity of cyclophosphamide in mice and determines its underlying mechanisms. Flavocoxid (Flavo) is a pot...
Characterization and Expression Analysis of Extradiol and Intradiol Dioxygenase of Phenol-Degrading Haloalkaliphilic Bacterial IsolatesNARA Subscribed
Haloalkophilic bacteria have a potential advantage as a bioremediation organism of high oil-polluted and industrial wastewater. In the current study, Haloalkaliphilic isolates were obtained from Hamralake, Wadi EL-Natrun, Egypt. The phenotype script, biochemical characters, and sequence analysis of bacterial-16S rRNA were used to identify the bacterial isolates; Halomonas HA1 and Marinobacter HA2 . These strains required high...
Simulations of nuclear magnetic resonance (NMR) signal from fluids contained in porous media (such as rock cores) need to account for both enhanced surface relaxation and the presence of internal magnetic field gradients due to magnetic susceptibility contrast between the rock matrix and the contained fluid phase. Such simulations are typically focussed on the extraction of the NMR T 2 relaxation distribution which can be rela...
