This study aimed to develop films based on collagen and <i>Jatropha mutabilis</i> stalk extracts (SEJM) to evaluate the scar repair process in rodents. SEJM demonstrated the presence of phenolic compounds, antioxidant activity (DPPH: IC₅₀ of 7.522 ± 0.068 μg mL⁻¹; β-carotene %: 83.770 ± 2.636), and antimicrobial action against different strains of <i>Staphylococcus aureus</i>. Furthermore, hydrolyzed collagen was combined with PVA, glycerol, and SEJM to produce healing films (C_SEJM).

This study investigates the potential of gum arabic, a polysaccharide-based biopolymer, for soil stabilization. Various types of sands are used to examine the strength and stiffness characteristics of gum arabic-treated sand. Three different biopolymer contents are used to investigate the influence of gum arabic on rheological behavior, the strength, and stiffness characteristics of treated sand. Rheological analysis indicated that both shear stress and viscosity remain almost constant for 24 h, regardless of biopolymer content. The rheological behavior, such as shear thinning and thickening, of hydrogel varies with biopolymer content. The compressive strength of treated specimens improved significantly within the range of 1.3–7.5 MPa after curing for 28 days. The shear wave measurements demonstrate enhanced stiffness across curing periods, with higher biopolymer contents demonstrating the most significant improvements. Microscopy image of the treated sand shows the effective bonding and cohesive network formed by gum arabic hydrogel, which filled pore spaces and reinforced the soil matrix.

In this study, the damage induced by heating in chemically treated hair subjected to acid straightening, bleaching, and the combination of both treatments is investigated. Previous results published by our group have already clarified certain aspects of the mechanism of action of acid straightening on hair fibers. In this new work, we show other relevant aspects to the hair care area with the aim to respond: how can we assist cosmetic product developers and consumers in understanding the changes caused by the combined use of chemical transformation procedures (specifically acid straightening and bleaching) and exposure to heat? By examining the thermal behavior of chemically treated hair fibers, we shed light on key aspects of both external (through Fourier transform infrared spectroscopy–attenuated total reflectance [FTIR/ATR] and scanning electron microscopy [SEM]) and internal (through ultra-small angle x-ray scattering [USAXS], small angle x-ray scattering [SAXS], and wide-angle x-ray scattering [WAXS]) changes. SAXS and WAXS structural analyses provided information on the internal structure and hierarchical organization of hair samples. While these techniques have been widely used to evaluate hair fibers, the effects of heating on their structure have been less explored. We examined the changes in the hierarchical arrangements as the fibers were heated in situ during the x-ray scattering experiments. It was possible to evaluate the specific regions where heat causes damage to both the cortex and the cuticle of the hair fiber, and the extent of these damages. Furthermore, it was observed that the bleached and straightened fiber undergoes more changes with the use of heat, due to the loss of important surface components, as shown by FTIR and SEM measurements.</p>","PeriodicalId":8866,"journal":{"name":"Biopolymers","volume":"117 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bip.70071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145740776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results demonstrated the effective synthesis of PAAm, PCS₂, and P(AAm/CS₂), with the copolymer having an average molecular weight of 187,673 Da.
