The hidden cost of the pool: environmental risk factors, clinical implications, strategies for prevention and treatment – a literature review

Quality in Sport
Dental erosion refers to the gradual loss of tooth structure caused by acids unrelated to bacteria. Competitive swimmers face a heightened risk due to frequent exposure to chlorinated pool water, often with low pH, which weakens enamel.

Ferritin‐Doped Nanoparticles Triggered Tumor‐Specific Darkening for Enhanced Photothermal Tumor Ablation and Immune Activation

Advanced Healthcare Materials, EarlyView.
Ferritin‐doped hybrid nanoparticles triggered accurate tumor‐specific hemorrhage for enhanced in situ photothermal therapy and evoked anti‐tumor immunity. Notably, HFn/GA‐Fe specifically induced tumor hemorrhage 12 h after intravenous injection, resulting in visible color darkening. Through photoacoustic imaging, tumor vessels could be clearly observed

Time cost associated with sports participation for athletes with high support needs: a time-motion analysis of tasks required for para swimming

BMJ Open Sport & Exercise Medicine, 2022
Objectives People with cerebral palsy and high support needs (CP&HSN) are profoundly inactive but also under-represented in studies evaluating physical activity interventions. Reasons for their exclusion have not been evaluated.

The Effect of Competitive Swimming on Oral Health Status [PDF]

, 2020
Objectives/Aims: Competitive athletes are often considered to be susceptible to bodily injury. It is now being realized that competitive swimmers are also at risk, specifically in the unsuspected realm of the oral cavity.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Inertial Effects on the Stress Generation of Active Fluids [PDF]

, 2017
Suspensions of self-propelled bodies generate a unique mechanical stress owing to their motility that impacts their large-scale collective behavior. For microswimmers suspended in a fluid with negligible particle inertia, we have shown that the virial ...
