While the impact of bacteriophages on fermented dairy foods, such as yogurt and cheese, is well-documented, such knowledge is comparatively limited for fermented soybean foods (FSFs). Most FSFs (such as Cheonggukjang, Miso, Thua Nao, and soy sauce) are traditionally produced using natural microbiota under less controlled conditions. This makes them more susceptible to unpredictable microbial dynamics, including phage interference. In this review, we examine the diversity and occurrence of bacteriophages associated with FSFs.

Degalactosylated xyloglucan (dXG), obtained through the partial enzymatic removal of galactose from xyloglucan, has demonstrated biocompatibility, anti-inflammatory activity, and excellent scaffolding potential for cells.

To address these limitations, this study explores interpenetrating hydrogel networks composed of kC and dXG. The resulting kC/dXG hydrogels demonstrate improved mechanical integrity due to the structural contribution of kC, while dXG imparts enhanced swelling capacity and surface adhesiveness.

A complete Freund's adjuvant-induced arthritis was used to test the <i>in vivo</i> activity in female Sprague-Dawley rats, which were divided into five groups: (1) normal control, (2) arthritic control, (3) methotrexate treatment (0.1 mg/kg), (4) crude sulfated polysaccharide (CSP) (5 mg/kg), and (5) CSP (10 mg/kg).

In addition, animals from the methotrexate and CSP (5 mg/kg, p.o.) groups had a substantial reduction in paw volume compared to other treatment groups. Methotrexate and CSP treatment dramatically decreased the levels of the investigated marker enzymes.

In this work, increasing the levels of BPA and PNP in the soil intensified their drastic effects on the biomass and photosynthetic pigments of tomato plants. Moreover, BPA and PNP induced osmotic stress on tomato plants by reducing soluble sugars and soluble proteins relative to control. The soil contamination with BPA and PNP treatments caused a decline in the levels of macro- and micro-elements in the foliar tissues of tomatoes while simultaneously increasing the contents of non-essential micronutrients. The Fourier transform infrared analysis of the active components in tomato leaves revealed that BPA influenced the presence of certain functional groups, resulting in the absence of some functional groups, while on PNP treatment, there was a shift observed in certain functional groups compared to the control. At the molecular level, BPA and PNP induced an increase in the gene expression of polyphenol oxidase and peroxidase, with the exception of POD gene expression under BPA stress. The expression of the thaumatin-like protein gene increased at the highest level of PNP and a moderate level of BPA without any significant effect of both pollutants on the expression of the tubulin (TUB) gene.
