Prediction of nocturnal hypoglycemia by an aggregation of previously known prediction approaches: proof of concept for clinical application.

Background And Objective: Nocturnal hypoglycemia (NH) is common in patients with insulin-treated diabetes. Despite the risk associated with NH, there are only a few methods aiming at the prediction of such events based on intermittent blood glucose monitoring data and none has been validated for clinical use. Here we propose a method of combining several predictors into a new one that will perform at the level of the best involved one, or even outperform all individual candidates.

A linear functional strategy for regularized ranking.

Regularization schemes are frequently used for performing ranking tasks. This topic has been intensively studied in recent years. However, to be effective a regularization scheme should be equipped with a suitable strategy for choosing a regularization parameter.

[Redox processes in the retina and tunic tissues of the rat eye in experimental alkalosis].

It is shown in experiments is vivo that development of experimental metabolic alkalosis in rats is followed by changes in redox processes in the eye retina and tunic. For the first two months of the experiment the number of sulphydryl group decreases, while that of disulphide ones of water-soluble proteins and low-molecular compounds increases. The amount of oxidized metabolites of glycolysis and of a cycle of tricarboxylic acids (pyruvate, oxaloacetate, alpha-ketoglutarate) increases relative to the reduced ones (lactate, isocitrate, malate), as well as activities of hexokinase, pyruvate kinase, NAD-dependent malate dehydrogenase, while activities of fructose diphosphatase, glucoso-6-phosphate dehydrogenase, glutathione peroxidase and glutathione reductase fall.
