Abstract The strain-generated potential (SGP) is a well-established mechanism in cartilaginous tissues whereby mechanical forces generate electrical potentials. In articular cartilage (AC) and the intervertebral disc (IVD), studies on SGP have focused fluid- ionic-driven effects, namely Donnan, diffusion streaming However, recent evidence has indicated direct coupling between strain potential. ...

The ratio of concentration of chloride in the aqueous humor compared with that in the plasma of rabbits, dogs, and human beings, was determined by the Schales and Sendroy methods. Consistent results were obtained in all the experiments by the Schales method with or without protein, and by the Sendroy method without protein. In the presence of protein, however, lower chloride concentrations were...

Ion-Driven Artificial Neural Signals In article number 2301037, Chang-Soo Han and co-workers create fully ion-driven artificial neural signals by mimicking double-Donnan effect of an excitable cell. This system not only generates electrical flowing desired ions, but can also be used as a bio-friendly, high-efficiency power source.

A new cationic gadolinium contrast agent is reported for delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC). The agent partitions into the glycosaminoglycan rich matrix of articular cartilage, based on Donnan equilibrium theory, and its use enables imaging of the human cadaveric metacarpal phalangeal joint.

background: peritoneal dialysis is one of the most prevalent types of dialysis prescribed to the patients suffering from renal failure. studies on the factors affecting the survival of these patients have mainly used log-rank test and cox analysis. the present study aimed to investigate the risk factors affecting short- and long term survival of patients on continuous ambulatory peritoneal dial...

results out of 66 patients, 61 (19 in group a, 20 in group b, and 22 in group c) completed the study period, and before intervention, all groups were equal in terms of quality and quantity variables (p > 0.05). after intervention, there was a significant difference between the three groups with regard to the variables of dialysis adequacy based on kt/v and urr to independent-t test and repeated...

this articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under dc electric field and b) a physico - mathematical description.a) gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at ph 12 by teteramethylethylene diamine. equlibrium properties of the resulting gels rods (water content, number of ca...
