Objectives: To evaluate the durability and value of 3 common suspension manual wheelchairs and to compare the results with those of previously tested lightweight and ultra-lightweight folding-frame wheelchairs.
Design: Standardized fatigue testing and cost analysis of 3 suspension manual wheelchairs from 3 different manufacturers.
Setting: A rehabilitation engineering center.
Specimens: Nine suspension manual wheelchairs.
Interventions: Wheelchairs were fitted with a standardized wheelchair test dummy and tested on a series of fatigue tests, consistent with those developed by the International Organization for Standardization. Main outcome measures Fatigue life (measured as the number of equivalent cycles completed) and value (equivalent cycles divided by cost) were compared among all wheelchairs.
Results: Analysis of variance revealed significant differences (P< or =.05) in the number of equivalent cycles among the suspension wheelchairs tested. When compared with previously tested ultra-lightweight and lightweight wheelchairs, the suspension wheelchairs failed to show significant improvements; however, significant improvements were found between individual suspension and lightweight wheelchairs.
Conclusions: We found little evidence to suggest that suspension manual wheelchairs provide advantages in terms of durability or value over standard lightweight and ultra-lightweight folding-frame wheelchairs.

Full automation of single-molecule localization microscopy (SMLM) is crucial for large-scale and high-throughput cellular imaging. It is well-known that SMLM typically consists of three major steps: immunofluorescence (IF) staining, optical imaging, and image processing. Currently, automation in optical imaging and image processing is almost complete; however, the automation of IF staining has been slow to advance, probably due to its complicated experimental operations.

Article Synopsis
- Optoelectrowetting technology allows for the manipulation of droplets by creating virtual electrodes, avoiding complicated physical circuitry in droplet control systems.
- Current limitations include the need for manual droplet positioning and lack of real-time feedback, which can lead to mismanagement and contamination of droplets.
- The paper introduces an intelligent control system that integrates optoelectrowetting with deep learning for real-time detection and automatic movement control of droplets, improving flexibility and accuracy in experiments, especially in biomedicine.

Objective: To evaluate the molluscicidal effects and costs of spraying 20% suspension concentrate of pyricloben-zuron sulphate (SCPS) with drones against in paddy environments, so as to provide insights into the extensive applications of pyriclobenzuron against .
Methods: On July 2022, a paddy field was selected from Nanchang City, Jiangxi Province as the study area, and 72 independent rectangular plots measuring 2 m × 1 m were allocated in the study area, with 1 m interval between each plot, and 20 snails gently placed in each plot. The activity of 25% wettable powder of pyriclobenzuron sulphate (WPPS) by manual spraying at doses of 0.
Accelerated production of human epithelial organoids in a miniaturized spinning bioreactor.

Conventional static culture of organoids necessitates weekly manual passaging and results in nonhomogeneous exposure of organoids to nutrients, oxygen, and toxic metabolites. Here, we developed a miniaturized spinning bioreactor, RPMotion, specifically optimized for accelerated and cost-effective culture of epithelial organoids under homogeneous conditions. We established tissue-specific RPMotion settings and standard operating protocols for the expansion of human epithelial organoids derived from the liver, intestine, and pancreas.
