A traditional source of natural bioactive compounds, mushrooms are used to synthesize biomaterials, thanks to their potential applications in the medicine, pharmacology and cosmetics industries. In this study, the vitamin C and E contents of the Hebeloma excedens mushroom species were determined as 64.2 mg/g and 38.6 mg/g, respectively. In the mineral substance analysis, the highest amount of magnesium (32.16 mg/g) and trace amounts of iron (0.22 mg/g) were detected. In the nanoparticles (AgNPs/He) synthesized using this mushroom species, the colour of the mixture first changed to dark brown and exhibited maximum absorption at 428 nm, corresponding to the surface plasmon resonance. Fourier transform infrared spectroscopy (FTIR) results revealed the binding properties of the biocomponents responsible for coating and stabilizing the nanoparticles. The resulting nanostructures were much more stable than the mushroom extract and showed strong antioxidant activity (22.93 mg/ml). A significant decrease in phenolic compounds was observed after the gastrointestinal digestion process applied to the mushroom extract and AgNPs/He samples (p < 0.05). However, a significant increase in the bioaccessibility of phenolic compounds was detected in AgNPs/He particles (p < 0.05). It was determined that there was a significant increase in the thermal stability, inhibition against lipid peroxidation (6.64 mg/ml) and antidiabetic activities (29.20 mg/ml) of silver structures synthesized using the green synthesis method. As a result, the existence and current potential of a new biomaterial suitable for cost-effective and large-scale production in the synthesis of AgNPs/He has been demonstrated for the first time.

“…The extremely small dimensions of these nanomaterials give them unique properties that open the way to many applications from energy storage [2][3] to biochemical engineering applications [4]. Among all the forms that nanomaterials can take, nanoparticles are in the forefront such as in dentistry applications [56], depollution of the environment [7][8], sustainable agriculture [9][10], optical components [11][12] and nanomedicine [13][14]. A civilizational issue concerns the fight against organic pollutants on a global scale [15] including the depollution of wastewater which requires the implementation of remediation processes [16][17].…”

Photo-degradation of Rhodamine B (RhB) in aqueous solution was use as a probe to assess the photocatalytic activity of Gadolinium oxide (Gd2 O3 ) nanoparticles in suspension under UV irradiation. The nanoparticles in suspension were prepared by a polyol method using gadolinium chloride hexahydrate (Gd2 Cl6 .6H2 O) and diethylene glycol (DEG) as starting precursors. The physico-chemical properties of the elaborated suspension are analyzed using X-ray diffraction (XRD), ultraviolet visible (UV-vis) and infrared (FTIR) spectroscopies, transmission electron microscopy (TEM) and viscosimetry. The Gd2 O3 nanoparticles in suspension were used as photocatalyst for the degradation of Rhodamine B (RhB) dye under irradiation with UV light. The results of the kinetic studies showed that the photodegradation reactions were followed by a pseudo first order reaction rate law over the first 30 minutes of monitoring. The elaborated Gd2 O3 nanoparticles suspension showed a great efficiency in the photocatalytic test without any addition of a co-catalyst, thus limiting the complexity of the further decontamination process of waste water.

“…To avoid or alleviate cell damage caused by ROS, plants stimulate their antioxidant enzyme systems, which are closely related to plant stress resistance [55]. CAT can prevent cell membrane damage, POD can remove excessive reactive oxygen species, MDA is the nal product of lipid peroxidation in plants, and the accumulation capacity of free proline represents the drought resistance of plants [54,[56][57][58]. It combines and cross-links with proteins on the cell membrane to destroy the structure and function of the bio lm, and its content can represent the degree of cell membrane damage [59].…”

Aegilops tauschii Coss. (2n = 2x = 14, DD) is a weed of wheat, competes for resources, performs better against different abiotic stresses, and is a rich genetic material source for wheat crop improvement programs. The effects of different drought stress levels on physiological and biochemical parameters and the expression profile of the drought resistance gene DRB were examined through greenhouse experiments. The physiological parameters (plant height, dry weight biomass, plant height, and leaf area-related parameters) fluctuated under different drought stress levels. Photosynthetic parameters (maximum (Fo’) and minimum (F’m) fluorescence, photochemical ((ΦPSII)), and non-photochemical quenching (qN)) were also affected by different drought stress levels, and their efficiency fluctuated with water availability. In the biochemical analysis, shallow significant changes occurred in peroxidase (POD), catalase (CAT), and proline content, while malondialdehyde (MDA) showed variation under different drought stress conditions. In the DREB gene expression analysis, eight populations showed high expression profiles compared to the control conditions in Ae. tauschii. The expression profiles in Ae. tauschii showed a high fold increase compared to the control condition, and DREB gene expression correlated with the changes in physiological and biochemical parameters.
