Comparative studies of the efficiency of MLW-1.3 and 1.8-hollow fiber dialyzers

Zeitschrift für Urologie und Nephrologie
I EngelhardtK Precht


Clinically contradictory results in the use of hollow-fibre dialysers with surfaces of 1.3 and 1.8 m2 prompted us to compare their efficiency under standard conditions. It was found that the efficiency does not increase proportionally to the enlargement of the dialyser surface. the reason for this is to be seen in: the supply of rinsing solution in the dialyser, blood flow, insufficient degassing, coating of the membrane with denatured protein and, last but not least, the body mass of the patient himself. For optimum dialysis an individually suited dialysis time can be calculated from these data for each patient.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
