The gene encoding the insulin-like androgenic gland hormone in an all-female parthenogenetic crayfish.

Male sexual differentiation in crustaceans is controlled by the androgenic gland (AG), a unique male endocrine organ that, in decapods, is located at the base of the 5th pereiopod. In these animals, the insulin-like androgenic gland hormone (IAG) is the major factor secreted from the AG to induce masculinization and maintain male characteristics. It has, however, recently been proposed that this hormone also plays a role in growth and ovarian development in females.

[Percutaneous transluminal angioplasty for vascular access in hemodialysis. Apropos of 53 operations].

Percutaneous transluminal angioplasty as stenosis treatment in hemodialysis arterio venous fistulae. About 53 cases. Percutaneous transluminal angioplasty was used 53 times to dilate 75 stenoses in 37 hemodialysed patients.

Pharmacokinetic monitoring of heparin therapy for regular hemodialysis.

Using a pharmacokinetic model for heparin prescription during hemodialysis leads to a precise monitoring of the coagulation time (CT) with 25% less heparin required. Two different populations were distinguished: The first group maintained stable sensitivity and elimination constant, permitting a stable prescription and giving stable CT values for up to 2 years. The other group exhibited wide variations of these parameters, necessitating daily dose monitoring.
