AI Article Synopsis
- Cold plasma (CP) technology is a new method in agriculture that enhances the surface properties of seeds, potentially improving their germination and crop yields.
- The study tested wheat seeds using direct (glow) and indirect (afterglow) low-pressure radio-frequency oxygen plasma, analyzing changes in seed surface chemistry and morphology through various advanced techniques.
- Results showed that prolonged direct CP treatment increased seed surface roughness and functionalization but slowed germination, reduced α-amylase activity, and negatively affected seedling root development.
Article Abstract
Cold plasma (CP) technology is a technique used to change chemical and morphological characteristics of the surface of various materials. It is a newly emerging technology in agriculture used for seed treatment with the potential of improving seed germination and yield of crops. Wheat seeds were treated with glow (direct) or afterglow (indirect) low-pressure radio-frequency oxygen plasma. Chemical characteristics of the seed surface were evaluated by XPS and FTIR analysis, changes in the morphology of the seed pericarp were analysed by SEM and AFM, and physiological characteristics of the seedlings were determined by germination tests, growth studies, and the evaluation of α-amylase activity. Changes in seed wettability were also studied, mainly in correlation with functionalization of the seed surface and oxidation of lipid molecules. Only prolonged direct CP treatment resulted in altered morphology of the seed pericarp and increased its roughness. The degree of functionalization is more evident in direct compared to indirect CP treatment. CP treatment slowed the germination of seedlings, decreased the activity of α-amylase in seeds after imbibition, and affected the root system of seedlings.

Graphene oxide (GO), renowned for its two-dimensional structure and exceptional fluorescence quenching capabilities, is a preferred choice for the construction of fluorescence biosensors. As the sensitivity demands for these sensors escalate, enhancing the fluorescence quenching performance of GO and reducing background fluorescence become paramount to optimize the sensor sensitivity. In this study, the use of cold plasma (CP) treatment with glucose solution as a reducing agent to refine GO into reduced graphene oxide (r-GO) with optimal fluorescence quenching abilities was explored.

Sperm cryopreservation is a useful storage technique in artificial insemination. Nanoparticles and nanovesicles such as exosomes are widely used in sperm cryopreservation procedures to alleviate cold-induced injury inflicted during sperm freezing. The objective of the present study was to examine the impact of varying concentrations of exosomes derived from seminal plasma added to a freezing extender on the quality of post-thawed bull sperm.

Introduction: Myocardial protection with cardioplegia is a crucial approach to mitigate myocardial damage during coronary bypass grafting surgery (CABG) with cardiopulmonary bypass (CPB). The major component of the del Nido cardioplegia solution, Plasma-Lyte A, is difficult to obtain in Iran due to high cost. The objective of the current study was to study if the lactated Ringer's solution as the base for del Nido solution (LR DN) usage is a viable option as a substitute for Plasma-Lyte A in adult patients presenting for CABG surgery.
