As the demand for egg white protein (EWP) alternatives grows due to concerns such as Salmonella contamination, avian influenza, and the increasing environmental awareness, plant-based proteins have gained attention as a promising solutionCompared to other legumes, adzuki beans are rich in sulfur-containing and hydrophobic aromatic amino acids, which may contribute to improved foaming properties.However, their functional potential remains largely unexplored.This study examined the foaming performance of adzuki bean protein isolate (API) relative to EWPs and soy protein isolate (SPI) under varying thermal and temporal conditions.API exhibited foam thickness and drainage comparable with those of EWPs and superior to SPI across 4 °C, 25 °C, and 83 °C.Confocal laser scanning microscopy (CLSM) and SEM revealed that API formed finer, more spherical foam structures with fewer ruptures, while SPI showed larger, unstable bubbles.Zeta potential and dual-fluorescent CLSM anal. indicated greater interfacial rearrangement in API, supported by its lower surface hydrophobicity and higher free sulfhydryl (-SH) content, which enhanced interfacial stiffness in rheol.Fourier-transform IR spectroscopy anal. further revealed that API, like EWPs, showed increased β-sheet formation under heat, contributing to thermal foam stability, whereas SPI exhibited the opposite trend.In a meringue cookie application, API showed a lighter batter with greater air incorporation than SPI, highlighting its practical potential.Overall, this study offers new insight into the structural and interfacial mechanisms governing foam formation and decay, supporting API′s potential as a promising plant-based alternative for aerated food systems.

Individuals with chronic ankle instability (CAI) exhibit deficits in postural control and muscle activation, with bilateral changes suggesting central alterations in sensorimotor function. However, differences in postural control and muscle activation between bilateral and unilateral CAI remain unclear. Understanding these differences is crucial for developing targeted rehabilitation strategies.

Do individuals with bilateral CAI, unilateral CAI, and healthy controls have differences in postural control and muscle activation?

18 individuals with bilateral CAI (bilateral), 18 individuals with unilateral CAI (unilateral), and 18 healthy controls (control) were recruited. To assess center of pressure (COP) and integrated electromyography (iEMG), participants performed 3 trials of single-leg stance tasks and lower extremity muscle activation was recorded simultaneously. One-way ANOVA was used to assess differences in the self-reported functional outcomes, postural control, and muscle activation among the three groups.

The bilateral group showed worse postural control in COP mediolateral velocity and COP anteroposterior velocity compared to the unilateral and control groups. However, the unilateral group showed similar postural control with the control group. The bilateral group showed greater iEMG in the tibialis anterior compared to the unilateral and control groups. The unilateral group showed lower iEMG in the tibialis anterior compared to the control group.

Individuals with bilateral and unilateral CAI show significant differences in postural control and muscle activation during single-leg stance, suggesting that the central nervous system may process sensorimotor function differently. Understanding these differences can guide personalized treatments, which may enhance patient outcomes and reduce recurrent sprain risk.

Individuals with chronic ankle instability (CAI) have deficits in force accuracy in evertors and hip abductors due to impaired neuromuscular control. Individuals with CAI rely more on visual information during force accuracy following lateral ankle sprain. To identify the effects of using stroboscopic glasses following a 4-week rehabilitation on force accuracy of ankle evertors, invertors, and hip abductors and visual reliance in individuals with CAI.

Randomized controlled clinical trial.

A total of 50 CAI individuals were assigned to a strobe or control group. The strobe group wore stroboscopic glasses during rehabilitation, while the control group did not. Force accuracy was measured at 10% and 20% of maximum voluntary isometric contraction (MVIC). Romberg ratios were calculated as strobe vision/eyes open to identify visual reliance.

The strobe group showed a greater force accuracy in 10% of evertors MVIC under the strobe vision than the control group. The strobe group showed a greater force accuracy in 10% of evertors MVIC under the strobe vision than with the eyes open. The strobe group showed an improved Romberg ratio in 10% of evertors MVIC between the pretest and posttest.

Stroboscopic glasses may offer clinicians a new means to reduce visual reliance, allowing them to utilize the somatosensory system more effectively around the foot/ankle complex. This may indicate reweighting of sensory systems in CAI individuals during rehabilitation.
