Numerical simulations of homogeneous crystal nucleation with a model for globular proteins with short-range attractive interactions showed that the presence of a metastable fluid-fluid critical point drastically changes the pathway for the formation of a crystal nucleus. Close to this critical point, the free-energy barrier for crystal nucleation is strongly reduced and hence, the crystal nucleation rate increases by many orders of magnitude. Because the location of the metastable critical point can be controlled by changing the composition of the solvent, the present work suggests a systematic approach to promote protein crystallization.

Albumin infusions are given far from always on the correct indications, and often there are alternatives that are cheaper and equally suitable. In septic or hypovolaemic shock, crystalline fluids are cheaper and equally efficacious for volume therapy. It is only in sporadic patients with a nephrotic syndrome that colloidal solutions such as albumin are indicated in hypovolaemia. Albumin infusion has no place in the combating of oedema. In decompensated hepatic cirrhosis with ascites, it appears useful to combine paracentesis with albumin infusion, to prevent renal insufficiency and hyponatraemia, but other colloidal fluids are probably equally suitable. Combating hypoalbuminemia as such is not useful in seriously ill patients; it is the underlying disease that should be treated.
