Summary: Stroke is a major public health concern and a leading cause of long-term disability. Dynamic body weight support (DBWS) systems are popular in clinical settings, but there is limited research comparing DBWS to standard of care (SOC) in inpatient settings. This study aimed to determine if incorporating DBWS into inpatient therapy offers greater improvement for acute ischemic stroke survivors compared to SOC.

Summary: This study aims to understand how healthy adults react to physical perturbations when transitioning from sitting to standing. The results show that the direction of perturbations had the most distinguishable change among participants, and as the perturbation intensities increased, participants required an increase in trunk movement to maintain balance. These findings provide important insights for designing future sit-to-stand perturbation-based training programs for individuals prone to falling.

Summary: The development of left ventricular assist device (LVAD) has been driven by the rise of heart failure in the setting of heart donor shortage. However, complications such as stroke and device thrombosis still occur due to hemodynamic changes. This study compared the hemodynamic characteristics of standard and spiral LVAD outflow cannula, with different anastomosis sites and the addition of a spiral inducing chamber. The results showed that the spiral LVAD cannula had a lower output velocity and lower region of low WSS value.

Summary: A cost-effective and eco-friendly method for synthesizing silver nanoparticles using pineapple leaves waste mediated by microwave-assisted extraction is presented. The green synthesis of AgNPs is accomplished through a simple reduction method utilizing silver nitrate. Various parameters, including silver nitrate concentration, incubation time, and sample volume, are employed to determine the optimal green synthesis condition. The microwave-assisted treatment of silver nanoparticles exhibits greater antimicrobial activity against Escherichia coli, Bacillus subtilis, and Staphylococcus aureus compared to nonmicrowave-assisted treatment.

Summary: Thermoelectric devices are important for renewable energy generation, offering compactness and emission-free operation. Iron disilicide composite materials prepared by eutectoid reaction show promise for thermoelectric applications. Doping with Mn and Co enhances carrier mobility and concentration, while Al and P lower thermal conductivity. In thin films, surface flatness is crucial to improve carrier mobility. The optimization of beta-FeSi2/Si composite materials at the nanoscale significantly enhances electrical conductivity and reduces thermal conductivity.
