General practitioners' role in cancer care: a French-Norwegian study.

Background: In cancer care, a GP's work is rarely defined clearly. Our aim was to assess GPs' work with cancer patients in France and in Norway, where the roles of the GP and the organization of the system are rather different.

Findings: A questionnaire with 40 closed-ended questions about GP involvement in diagnosis, treatment, follow-up and terminal care was constructed and mailed to samples of GPs.

[Guidelines and practices for type 2 diabetes. Patients' and doctors' preconceptions prevent effective patient education].

Background: Health insurance data show that general practitioners (GPs) do not strictly apply clinical practice guidelines for the management of patients with type 2 diabetes.

Method: The Health insurance fund of the Centre region assessed doctors' practices in diabetes management and found sharp disparities. Our study sought to explain these differences by questioning (through interviews and questionnaires) a cross-section of GPs and patients with diabetes.

Glycosylation characteristics of the mouse liver lactogenic receptor.

The structural characteristics and glycosylation properties of the lactogenic receptor were examined in 3-[(3-cholamidopropyl)dimethylammonio]-1-propane sulfonate (CHAPS)-solubilized plasma membranes from female mouse liver. The specific binding of the radioiodinated human growth hormone [( 125I]hGH) was displaced with an equivalent potency by both hGH and prolactin. After a mild neuraminidase treatment, this binding was increased by 40%, as a result of an increase in receptor affinity.
