“…Even though starch show low mechanical strength and insufficient water resistance, it can be enhanced by mixing it with hydrophobic polymers like poly-vinyl alcohol (PVA). Addition of starch with PVA based gel greatly improves the quality of the hydrogel specially for wound dressing applications 8,9 . There are many factors in the development of hydrogels from starch raw materials that greatly affects its properties.…”

Wound dressing is a vital component of wound infection management specially by immunocompromised patients due to accidents that caused injuries. Biodegradable hydrogel-based wound dressings are being developed to acquire the advantage of high swelling capacity and being environment friendly at the same time. The study involves development of hydrogels using solution casting method with different ratio of rice bran starch. Mechanical properties such as tensile strength and swelling capacity were determined. The hydrogel developed with 7% starch emerged with comparable tensile strength and swelling capacity with the available wound dressing in the market. FT-IR spectra confirmed the crosslinking of PVA and starch while SEM images revealed that the hydrogel is not porous. Drug loading capacity of the hydrogel was determined to be 83.48% with PBS which is higher than with water. Results suggest that the developed hydrogel has great potential for wound dressing application with the advantage of being biodegradable.

“…Figure 1c shows the hydrogen bonding interactions between polymer networks and the free radical reaction sites produced by PVA and PVP under irradiation conditions. [43][44][45][46] EBI induced molecular polymerization and cross-linking is a fast and efficient method for preparing ionogel materials. [36,43] The three molecules, H 2 O, PVA, and PVP, produce free radicals after being irradiated by the electron accelerator (Figure S1a, Supporting Information).…”

Skin, characterized by its distinctive gradient structure and interwoven fibers, possesses remarkable mechanical properties and highly sensitive attributes, enabling it to detect an extensive range of stimuli. Inspired by these inherent qualities, a pioneering approach involving the crosslinking of macromolecules through in situ electron beam irradiation (EBI) is proposed to fabricate gradient ionogels. Such a design offers remarkable mechanical properties, including excellent tensile properties (>1000%), exceptional toughness (100 MJ m−3), fatigue resistance, a broad temperature range (−65–200°C), and a distinctive gradient modulus change. Moreover, the ionogel sensor exhibits an ultra‐fast response time (60 ms) comparable to skin, an incredibly low detection limit (1 kPa), and an exceptionally wide detection range (1 kPa–1 MPa). The exceptional gradient ionogel material holds tremendous promise for applications in the field of smart sensors, presenting a distinct strategy for fabricating flexible gradient materials.

“…3, which includes mycotoxins that are not classified as carcinogenic to humans [ 42 ]. The toxicity of ZEN in vivo was studied by many research mostly reported the hazardous effect of Zearalenone on the reproductive systems either in male or female [ 42 ], also there was a specific concern about the lipid peroxidation of membranes which is included in the means by which ZEN exert its toxic action on human [413, another concern was the findings of [ 44 ] who demonstrated the ability of Zearalenone to disrupt liver functions and affect the liver thoroughly to the degree of suppression of cytochrome P450 in the liver results of our work gave clear data about the distribution of Zearalenone in different body organs which in turn could reveal the most susceptible organs that could suffer from Zearalenone/derivatives toxicity [ [121] , [122] , [123] , [124] , [125] , [126] , [127] , [128] , [129] , [130] , [131] , [132] , [133] , [134] , [135] , [136] , [137] , [138] , [139] , [140] , [141] , [142] , [143] , [144] , [145] ]. By examining the beneficial effect of L. plantarum on the organ exposure to Zearalenone/derivatives, results revealed that although the administration of L. plantarum did not significantly alter the accumulation of [ 125 I]-iodo-ZEN in different mice organs and there were observed similarity in the pattern of Zearalenone distribution through different organs yet there was marked reduction in the Zearalenone concentration in the ovary and that was observed from the 1st 5 min of administration, and since the ovaries are considered the most sensitive (target) organ of Zearalenone toxicity that could provide additional benefit for the use of LAB as it was reported to demonstrate anti-inflammatory, anti-genotoxic and improve ovarian fertility [ 45 ], the decline in the accumulation of [ 125 I]iodo ZEN in mice organs may be attributed to the lactic acid bacterial capability to bind and/or alter ZEN to other compound [ 9 ].…”
