Urea is also known as carbamide, an inexpensive and eco-friendly additive for starch functionalization. This article reviews the potential role of urea in starch modification, with the prominence of the mechanism of urea action, alterations in the starch structure and functional properties. In addition, current literature conveys the prospective effect of urea in fabricating starch films for food packaging, and the relevant areas that need to be covered in the forthcoming research are specified at the end of the article section. Urea can modify the diverse physico-chemical and functional properties of starch. Starch-based films exhibit pronounced effects on their mechanical and barrier properties upon the incorporation of urea, although this effect strongly depends on the urea content and degree of substitution (DS). Overall, urea holds great potential for use in the starch and bioplastic film industries, as it produces biocompatible derivatives with desirable performance.

The growing demand for sustainable solutions in agriculture, driven by global population growth and increasing soil degradation, has intensified the search for sustainable soil conditioners. This study investigated the impact of adding nanoclay (NC) and nano lignin (NL) to thermoplastic starch (TPS) on its physical, chemical, and thermal properties, its effectiveness as a soil conditioner, and its resistance to UV-C degradation. TPS nanocomposites were prepared with varying NC (3 %, 5 %, 7 %) and NL (0.

Two novel yeast strains, NYNU 236247 and NYNU 23523, were isolated from the leaves of Hance, collected in the Tianchi Mountain National Forest Park, Henan Province, central China. Phylogenetic analysis of the D1/D2 domain of the large subunit rRNA gene and the internal transcribed spacer (ITS) region revealed the closest relatives of the strains are three described species: , and . The novel species differed from the type strains of these three species by 12 to 22 nucleotide substitutions and 1 gap (~2.

Palmar hyperhidrosis is common condition that is challenging to treat. Nonsurgical treatments include topical antiperspirants, iontophoresis, anticholinergic drugs and botulinum toxin injections. To evaluate the safety and efficacy of ablative fractional laser therapy, combined with topically applied botulinum toxin versus its injection for the treatment of hyperhidrosis.

The relationship between the gut microbiota (GM) and the health of human beings has been a topic of growing interest in the last few years. Legumes are a rich source of indigestible carbohydrates, including resistant starch (RS), which are substrates of the GM. The aim of this study was to evaluate the effect of the indigestible fraction of legumes on the fecal microbiota of normal-weight (NW) and obese (O) donors.
