Article Abstract
In commercial Dungeness crab fishing vessels, the block pulls crab pots for harvesting and typically positions them to the side of vessels, rather than the sorting tables on board. Consequently, fishermen must reach outside the vessel to grab the pots, posing increased risk of musculoskeletal and fall-related injuries. To investigate the effects of block design on these risks, 25 participants in a repeated-measures laboratory study handled a pot under two block conditions: away-from-table (conventional setting) and above-table (intervention). Low back and shoulder muscle activities, angles, moments, perceived exertion, and postural stability were measured. The results showed reduced L5/S1 and shoulder moments and angles; decreased muscle activities in the low back, shoulders, and upper extremities; and lower perceived exertion ratings and postural sway measures with the intervention. These findings indicate that positioning the pot closer to fishermen onboard could reduce the injury and fall risk associated with crab pot handling.

Image deblurring and compression-artifact removal are both ill-posed inverse problems in low-level vision tasks. So far, although numerous image deblurring and compression-artifact removal methods have been proposed respectively, the research for explicit handling blur and compression-artifact coexisting degradation image (BCDI) is rare. In the BCDI, image contents will be damaged more seriously, especially for edges and texture details.

Background: The 23-valent pneumococcal polysaccharide vaccine reduces the risk of pneumonia among adults by 38% to 46%. However, only a few older adults in resource-limited areas of China have received the pneumococcal vaccination. Pay-it-forward is a social innovation that offers participants free or subsidized health services and a community-engaged message, with an opportunity to donate to support subsequent recipients.

Microglia regulate neuronal circuit plasticity. Disrupting their homeostatic function has detrimental effects on neuronal circuit health. Neuroinflammation contributes to the onset and progression of neurodegenerative diseases, including Alzheimer's disease (AD), with several microglial activation genes linked to increased risk for these conditions.

Zika virus (ZIKV) has emerged as a rising concern in global health in recent years. The role of PD-1/PD-L1 immune checkpoint in acute ZIKV infection remains to be understood. In this study we demonstrated the activation of PD-1/PD-L1 immune checkpoint by ZIKV.
