The biomechanical implications of lacunar and perilacunar microarchitecture on microdamage accumulation in cortical bone.

: This study aimed to explore how the microarchitectural features of lacunae and perilacunar zones impact the biomechanics of microdamage accumulation in cortical bone, crucial for understanding bone disorders' pathogenesis and developing preventive measures. : Utilizing the phase field finite element method, the study analyzed three bone unit models with varying microarchitecture: one without lacunae, one with lacunae and one including perilacunar zones, to assess their effects on cortical bone's biomechanical properties. : The presence of lacunae was found to increase microcrack initiation risk, acting as nucleation points and accelerating microcrack propagation.

Oyster powder supplementation enhances immune function in mice partly through modulating the gut microbiota and arginine metabolism.

Oysters are well-known for their health benefits such as immuno-modulatory functions. The intestinal microbiome serves as a key mediator between diet and immune regulation. This study aimed to investigate whether oyster consumption could alleviate cyclophosphamide (Cy)-induced immunosuppression by promoting intestinal homeostasis.

Transcriptomic and metabolomic analysis reveals the molecular mechanism of exogenous melatonin improves salt tolerance in eggplants.

Introduction: Melatonin significantly enhances the tolerance of plants to biotic and abiotic stress, and plays an important role in plant resistance to salt stress. However, its role and molecular mechanisms in eggplant salt stress resistance have been rarely reported. In previous studies, we experimentally demonstrated that melatonin can enhance the salt stress resistance of eggplants.

Evaluating Older Adults' Engagement and Usability With AI-Driven Interventions: Randomized Pilot Study.

Background: Technologies that serve as assistants are growing more popular for entertainment and aiding in daily tasks. Artificial intelligence (AI) in these technologies could also be helpful to deliver interventions that assist older adults with symptoms or self-management. Personality traits may play a role in how older adults engage with AI technologies.

MC-LR induces and exacerbates Colitis in mice through the JAK1/STAT3 pathway.

Inflammatory bowel disease (IBD) is a complex gastrointestinal disorder attributed to genetic and environmental factors. Microcystin-leucine-arginine (MC-LR) is an environmental toxin that accumulates in the gut and produces intestinal damage. The aim of this study was to investigate the effects of exposure to MC-LR on development and progression of IBD as well examine the underlying mechanisms of microcystin-initiated tissue damage.
