In vivo application of potent probiotics for enhancing potato growth and controlling Ralstonia solanacearum and Fusarium oxysporum infections.

Plant probiotics are live microbial cells or cultures that support plant growth and control plant pathogens through different mechanisms. They have various effects on plants, including plant growth promotion through the production of indole acetic acid (IAA), biological control activity (BCA), and production of cellulase enzymes, thus inducing systemic resistance and increasing the availability of mineral elements. The present work aimed to study the potential of Achromobacter marplatensis and Bacillus velezensis as plant probiotics for the field cultivation of potatoes.

An Optical Universal Plasmon-Based Biosensor for Virus ‎‎Detection.

Purpose: Kretschmann-configuration has been used as a subwavelength framework to detect tiny ‎alterations of the refractive index of biomaterials. However, most of the theoretical assessment of such configuration ‎is usually based on the plane wave excitation transfer matrix method (TMM) of prism-‎coupled to thin metal film supporting plasmonic modes. Accordingly, a better theoretical framework ‎than the plane wave approximation is indispensable for reliable and accurate assessments and ‎simulations.

Radioiodination of balsalazide, bioevaluation, and characterization as a highly selective radiotracer for imaging of ulcerative colitis in mice.

This work focuses on tracking ulcerative colitis in mice. High labeling yield and radiochemical purity were achieved for the formation of a [ I]balsalazide radiotracer at optimum conditions of oxidizing agent content (chloramines-T [Ch-T], 75 μg), substrate amount (100 μg), pH of reaction mixture (6), reaction time (30 min), and temperature (37°C), using radioactive iodine-125 (200-450 MBq). The radiolabeled compound, [ I]balsalazide, was stable in serum and saline solution during 24 h.
