Fatigue and cognitive symptoms in patients with diabetes: relationship with disease phenotype and insulin treatment.

Neurobehavioral symptoms are frequently reported in patients with diabetes. Nevertheless, the characterization of the specific symptom dimensions that develop in diabetic patients with respect to disease phenotype and treatment status remains obscure. This study comparatively assessed fatigue symptoms and cognitive performance using a dimensional approach in 21 patients with insulin-treated type 1 diabetes, 24 type 2 diabetic patients either insulin-free or undergoing insulin treatment for at least six months, and 15 healthy subjects.

[Fixation and immunological reactivity of parasitic protozoa in sol-gel matrices].

Parasitic protozoa have been entrapped within sol-gel silica matrices. Stationary phase promastigote cells of Leishmania donovani infantum are mixed with a silicon alkoxide solution. They remain trapped within the growing oxide network formed upon hydrolysis and condensation of the alkoxide.
