Short-term effects of metformin in type 2 diabetes.

Background: Although metformin is widely used in the management of type 2 diabetes, its mechanism(s) of action is not fully known, and there have been remarkably few reports on short-term effects of the drug. Here, we examined the early effects on glucose and lipid metabolism and on certain adipose tissue and inflammatory markers during treatment for 28 days.

Methods: Twenty-one patients were randomized to metformin (n = 16) or placebo (n = 5) and studied at baseline, 1, 2 and 4 weeks with blood sampling and oral glucose tolerance tests (OGTT).

Experiments with Safe muARTMAP : effect of the network parameters on the network performance.

Fuzzy ARTMAP (FAM) is currently considered to be one of the premier neural network architectures in solving classification problems. One of the limitations of Fuzzy ARTMAP that has been extensively reported in the literature is the category proliferation problem. That is, Fuzzy ARTMAP has the tendency of increasing its network size, as it is confronted with more and more data, especially if the data are of the noisy and/or overlapping nature.

Survival enhancement through food sharing: a means for parental control of natal dispersal.

The value of food sharing among relatives is analyzed for a situation where fitness equals survival. In seasonal environments the minimum food abundance may set a limit to group living. Delayed dispersal is predicted to be linked to relaxed winter competition and high parental survival.

A comparison of the Glasgow Coma Scale and the Reaction Level Scale (RLS85).

The Glasgow Coma Scale (GCS) and the Reaction Level Scale (RLS85) were compared for rating neurosurgical patients in regard to ranking order of deficit severity, interobserver variability, and coverage for relevant factors. Four physicians, four registered nurses, and four assistant nurses performed 72 pairwise ratings on 47 neurosurgical patients. The rank correlation between the GCS sum score and the RLS85 was -0.

Assessment of responsiveness in acute cerebral disorders. A multicentre study on the reaction level scale (RLS 85).

A new scale for assessment of overall responsiveness, the Reaction Level Scale (RLS 85), which has been shown to have better reliability than the Glasgow Coma Scale (GCS), has been tested in four neurosurgical departments regarding inter-observer agreement and coverage i.e. the proportion of patients that could be assessed by the scale.
