There is insufficient evidence on the utility of potassium-binding resins in patients with end-stage renal disease on dialysis. In addition, their poor tolerability raises concerns of patient adherence. We aimed to assess the efficacy of calcium resonium and investigate the

In pediatric patients at risk of hyperkalemia there are limited treatment or preventive alternatives for this electrolyte imbalance. Oral or rectal sodium polystyrene sulfonate (SPS) has several potential adverse effects, and dietary potassium restriction may compromise nutrition. Pretreatment of infant

Polyelectrolyte multilayers (PEMs) deposited on flexible supports are promising candidates for many applications ranging from controlled wettability over stimuli responsive nanovalves to lithography free surface structuring. Since many potential applications involve elongation of these films, we investigated the effect of

Osseointegration of metallic implants used in orthopedic surgery requires that osteoprogenitor cells attach and adhere to the surface, then proliferate, differentiate into osteoblasts, and finally produce mineralized matrix. Because the ability of progenitor cells to attach to a scaffold surface

Patterned arrays of light-responsive microchambers are suggested as candidates for site-specific release of chemicals in small and precisely defined quantities on demand. A composite film is made of poly(allylammonium)-poly(styrene sulfonate) multilayers and gold nanoparticles incorporated between subsequent stacks of polyelectrolytes.
