“…Most crystallographic studies of p53 have focused on the central core (residues 94-292) due to its stability and function. [7][8][9] This region of the protein interacts with the genetic material through its DNA binding domain (DBD) and plays a critical role in DNA repair. [8][9][10] Each codon in the DBD is associated with cancer-related mutations, with 25% of mutations residing at six "hotspots" in GBM.…”

Composite membranes were prepared from an aqueous solution of poly(vinyl alcohol) (PVA) and silver sulphate. The silver nanoparticles were generated in situ before crosslinking PVA matrix by reduction of silver ions using sodium borohydride. Physico-chemical properties of the resulting composite membranes were studied using Fourier transform infrared spectroscopy (FTIR), UV-vis spectroscopy (UV-vis), thermogravimetric analysis (TGA), Wide-angle X-ray diffraction (WAXD), scanning electron microscopy (SEM), and universal testing machine (UTM). The UV-vis spectrum shows a single peak at 410 nm due to surface plasmon absorption of silver nanoparticles. This surely specified that silver nanoparticles are generated in PVA matrix. The membranes were under go pervaporation (PV) for separation of water from isopropanol at different temperatures. The results indicated that hydrophilicity and amorphous nature of the membranes were increased with increasing silver nanoparticles in PVA matrix. The swelling and separation performance of the membranes were studied. Both permeation flux and separation factor were increased with increasing silver nanoparticles in PVA matrix. The results showed that the membrane containing 2.5 mass% of Ag salt exhibited excellent PV performance. The values of total flux and flux of water are almost closed to each other, indicating that membranes could be effectively used to break the azeotropic point of water-isopropanol. The long-term test was performed at room temperature and ascertained that membranes were durable up to 30 days for the dehydration of IPA. On the basis of the estimate Arrhenius activation energy values, the efficiency of the membranes was discussed. The calculated DH s values are negative for all the membranes, indicating that Longmuir's mode of sorption is predominant.

“…Silver (Ag) nanoparticles have been found to have applications in various fields such as intercalation of materials for electrical batteries [2], optical receptors [3], polarizing filters, catalysts in chemical reactions, biolabelling [4], sensors [5], bioactive materials [6], signal enhancers in surface-enhanced Raman scattering (SERS)-based enzyme immunoassay [7] and antimicrobial agents [8]. Ag is known for its antimicrobial properties and has been used for years in the medical field for antimicrobial applications; it has even been shown to prevent HIV binding to host cells [9][10][11][12][13].…”

Nanocomposite films with dual-surface, silver (Ag) layers and silver-polyvinyl alcohol (Ag-PVA) bulk layers were prepared by Tollen's reagent using β-D-glucose as a green reducing agent in water as an environmentallyfriendly solvent and in PVA as a bio-friendly polymer. The gradual color change of Ag in PVA solutions from colorless to light brown and then to brown, and finally dark brown, indicated the formation of Ag nanoparticles in the bulk of the PVA solution which finally formed Ag layers on the inner side of the glass. Energy dispersive X-ray (EDX) analysis and X-ray diffraction (XRD) were used to characterize the nanocomposite films with two surfaces. The Ag content of the Ag layers reached 93% with a higher crystallinity. The Ag content of the Ag-PVA bulk layers reached 10.8% with a lower crystallinity due to incorporation of Ag nanoparticles in the polymer chains. The structure and morphology of the two surfaces were confirmed by scanning electron microscopy (SEM).
