    Abstract This study aimed to characterize the physical-chemical and biological properties of pectin (PC)/chia seed mucilage (CM) membranes. PC/CM [100/0 (control), 80/20%, 60/40%, and 40/60% w/w] membranes were prepared using the casting method. The membranes (PC/CM) were thin, yellow, lightly opaque (≈10%) and capable of blocking light UVB (between 66 at 52%). SEM analysis showed the presence of aggregates in the shape of a sphere (≈13 µm) and ovoid (≈25 µm). The proportion of 80/20 showed an increase in tensile strength (29%) and elastic modulus (19%) when compared to the control. FTIR analysis exhibited intermolecular interactions between PCPC, PC-CM, and CM-CM… More > Graphic Abstract

    Abstract Experiments of soiling effects on the performances of a PV panel have been performed using dust collected from two sites in the region of Agadir-Morocco. The optical transmittance of the front glass was found to depend on the nature and density of dust. The nature of dust was studied by means of scanning electron microscopy and energy dispersive x-ray spectroscopy. It was found that the granulometry of dust particles depends on the study area. For a dust density of around 20 g/m², the maximum power Pmax of the solar panel decreases drastically from 30 to 20 W for the (HP)… More > Graphic Abstract

    Abstract Arbuscular mycorrhizal (AM) fungi are widely distributed in various habitats, and the community composition varies in response to the changing environmental conditions. To explore the response of community composition to the succession of saline-alkali land, soil samples were collected from three succession stages of Songnen saline-alkali grassland. Subsequently, the soil characteristics were determined and the AM fungi in soil samples were analyzed by high-throughput sequencing. Then, the response relationship between community composition and soil characteristics was studied by Canonical correlation and Pearson analyses. The soil properties improved with the succession of saline-alkali grassland. There was no significant difference in alpha… More >

    LORIS RIZZELLO1,2,3, VALERIA DE MATTEIS4,*

    BIOCELL, Vol.46, No.11, pp. 2369-2380, 2022, DOI:10.32604/biocell.2022.021059

    Abstract The SARS-CoV-2 outbreaks highlighted the need for effective, reliable, fast, easy-to-do and cheap diagnostics procedures. We pragmatically experienced that an early positive-case detection, inevitably coupled with a mass vaccination campaign, is a milestone to control the COVID-19 pandemic. Gold nanoparticles (AuNPs) can indeed play a crucial role in this context, as their physicochemical, optics and electronics properties are being extensively used in photothermal therapy (PTT), radiation therapy (RT), drug delivery and diagnostic. AuNPs can be synthesized by several approaches to obtain different sizes and shapes that can be easily functionalized with many kinds of molecules such as antibodies, proteins, probes,… More >

    Abstract

    In rice, high concentration of lead (Pb) can cause phyto-toxicity affecting several physiological functions. Cultivation of rice varieties that are resistant to Pb-induced oxidative stress is an important management strategy in Pb-contaminated soils. In the current study, we evaluated four different rice cultivars for their response to Pb-induced stress. Three japonica type cultivars X-Jigna, Ediget, and Furat, and one Indica type cultivar Amber 33 were grown in soil containing different Pb concentrations (0 mM, 0.6 mM, and 1.2 mM). The soil was treated with 0 mM or 0.6 mM or 1.2 mM Pb solution one month prior to rice seedling… More >

    ALFONSO BLÁZQUEZ-CASTRO1,2,*, JUAN CARLOS STOCKERT2,3

    BIOCELL, Vol.45, No.4, pp. 849-862, 2021, DOI:10.32604/biocell.2021.015900

    Abstract Melanins (eumelanin, pheomelanin, and allomelanin) represent a very, if not the most, important group of biological pigments. Their biological roles are multiple, from photoprotection to antioxidant activity, heavy metal disposal or the myriad uses of color in organisms across all Phyla. In the first part of this review, eumelanin biology and some chemical aspects will be presented, as well as key physico-chemical features that make this biological pigment so interesting. The principal characteristics of the melanocyte, the melanin-synthesizing cell in mammals, will also be introduced. Transformed melanocytes are the cause of one of the most devastating known cancers: the malignant… More >
