Self-assembling nanoparticles for intra-articular delivery of anti-inflammatory proteins.

Rachel E Whitmire et al.

Biomaterials, 33(30), 7665-7675 (2012-07-24)

Intra-articular delivery of therapeutics to modulate osteoarthritis (OA) is challenging. Delivery of interleukin-1 receptor antagonist (IL-1Ra), the natural protein inhibitor of IL-1, to modulate IL-1-based inflammation through gene therapy or bolus protein injections has emerged as a promising therapy for

Amniogenic somatopleure: a novel origin of multiple cell lineages contributing to the cardiovascular system.

Rieko Asai et al.

Scientific reports, 7(1), 8955-8955 (2017-08-23)

The somatopleure is the amniotic primordium in amniote development, but its boundary to the embryonic body at early embryonic stages and the fate of cells constituting this structure are not well characterized. It also remains unclear how cells behave during

Light-assisted delithiation of lithium iron phosphate nanocrystals towards photo-rechargeable lithium ion batteries.

Andrea Paolella et al.

Nature communications, 8, 14643-14643 (2017-04-11)

Recently, intensive efforts are dedicated to convert and store the solar energy in a single device. Herein, dye-synthesized solar cell technology is combined with lithium-ion materials to investigate light-assisted battery charging. In particular we report the direct photo-oxidation of lithium
