Here, we present a cost-effective protocol to differentiate bovine fibro-adipogenic progenitors in a thin hydrogel sheet adherent to 96-well plates. We describe steps for the embedding and culturing of cells in alginate sheets, culture maintenance, and analysis. Compared to alternative three-dimensional (3D) models such as hydrogel-based microfibers, this approach simplifies automation while retaining efficient maturation of adipocytes. Embedded cells are still subjected to a 3D environment, but the sheets can be handled and analyzed like two-dimensional cultures.

Stable hollow-type microspheres (MSs) have been fabricated using α-synuclein (αS), an amyloidogenic protein, via freeze-induced protein self-assembly. This assembly process involves three steps: rapid freezing to form spherical protein condensates from αS oligomers, frozen annealing to form a crust on the condensate and freeze-drying to create an interior lumen via the three-dimensional (3D) coffee-stain effect. The crust produced during the frozen-annealing step is a β-sheet-mediated protein structure that is presumed to be created at the quasi-liquid layer of the protein-ice interface and thus contributes to the stability of MSs in aqueous solutions at room temperature without any additional surface stabilization.

Tissue gliding and mobility are paramount to the success of penile procedures. While postoperative healing is intended to protect, repair, and nourish injured tissues, an overzealous response often leaves painful and debilitating tethering between the corpora, including nerves, and surrounding tissues. This tethering interferes with the intended outcomes of surgery by preventing necessary gliding.

This research explored the influence of varying sodium alginate (SA) and egg white protein (EWP) ratios (1:2, 2:3, 1:1, 3:2, 2:1, v/v) on the structural and gel characteristics of chicken myofibrillar protein (MP) gels. The findings showed that containing SA and EWP significantly improved (P < 0.05) the water-holding capacity (up to 95.

Newly formed playas, such as those resulting from the desiccation of Lake Urmia (LU) in northwest Iran, are significant global dust sources with implications for human health and the environment. Stabilizing these surfaces affordably can be achieved using locally sourced magnesium-enriched brine. To evaluate this approach, for LU playa, we examined the accumulation of ions, minerals deposition, and salt crust (Cr) formation in LU brine under both natural and laboratory conditions.

The widespread use of synthetic plastics in packaging materials poses significant environmental challenges, prompting the search for biobased, biodegradable, and non-toxic alternatives. This study focuses on improving high-yield pulps (HYPs) as sustainable materials for packaging. Enhancing wet strength and barrier properties of papers from bleached chemi-thermomechanical pulps (BCTMPs) is crucial for their application in water- and air- resistant wrappers.
